R- add empty columns to a dataframe with specified names from a vector -

i have dataframe, df, a number of columns of data already. have vector, namevector, full of strings. need empty columns added df names of columns namevector. i trying add columns loop, iterating on each string in namevector. for (i in length(namevector)) { df[, i] <- na } but left error. error in [<-.data.frame ( *tmp* , , i, value = na) : new columns leave holes after existing columns alternatively, have thought of creating empty dataframe correct names, cbind-ing 2 dataframes not sure how go coding this. how go resolving this? the problem code in line: for(i in length(namevector)) you need ask yourself: length(namevector) ? it's 1 number. you're saying: for(i in 11) df[,i] <- na or more simply: df[,11] <- na that's why you're getting error. want is: for(i in namevector) df[,i] <- na or more simply: df[,namevector] <- na

vba - Matching excel value of column A and E to a name in column B and D -

basically have huge excel file numbers assign name (i start name unknown) | b 123456 | unknown 456875 | unknown2 assign sequenced number different values of rows. if column a2 = column e25, replace value of d25 unknown2 does make sense? i looking macro automatically it's clear enough me understand you... you have numbers in column , d - each number want specific name. the names should listed in column b (for numbers in a) , column e (for numbers in d). if there numbers in in d, too, these numbers share same name. try code: sub test() dim rng range dim long, j long, k long, l long dim firstaddress string, foundaddress string = 1 rows.count - 1 if isempty(cells(i, 1).value) exit next j = 1 rows.count - 1 if isempty(cells(j, 4).value) exit next j set rng = range("a1:a" & & ", d1:d" & j) l = 1 k = 1 + j if k < firstaddress = rng.find(cells(l, 1).value, lookat:=xlwhole, matchca

i have developed rather extensive http server written in python utilizing tornado. without setting special, server blocks on requests , can handle 1 @ time. requests access data (mysql/redis) , print out in json. these requests can take upwards of second @ worst case. problem request comes in takes long time (3s), easy request comes in after take 5ms handle. since first request going take 3s, second 1 doesn't start until first 1 done. second request takes >3s handled. how can make situation better? need second simple request begin executing regardless of other requests. i'm new python, , more experienced apache/php there no notion of 2 separate requests blocking each other. i've looked mod_python emulate php example, seems block well. can change tornado server functionality want? everywhere read, says tornado great @ handling multiple simultaneous requests. here demo code i'm working with. have sleep command i'm using test if concurrency works

c++ - System exception handling on different platforms -

basically, how catch exceptions on mac/linux? is, exceptions, not intrinsic language, segfaults & integer division. compiling on msvc, __try __except perfect because stack handling allows catch exceptions , continue execution lower down stack. now, extend program other platforms (mainly ones mentioned), have no idea how exception handling works on these platforms work. far understand, it's handled through posix signals? , of such, wont allow handle exception , continue lower down stack? edit: valid (pseudo code)? see it, leave c++ blocks correctly , dont indulge myself in ub. jmp_buf buffer; template< typename func > protected_code(func f) { if(!setjmp(buffer) { f(); } else { throw std::exception("exception happened in f()"): } } void sig_handler() { longjmp(buffer); } int main() { sigaction(sig_handler); try { protected_code( [&]

say have protocol protocol a: class { func configure(view: uiview) } now want conform protocol, using uilabel subclass of uiview final class b: { init() {} func configure(view: uilabel) { } } but errors type b not conform protocol a it seems swift needs same type stated in protocol. works final class b: { init() {} func configure(view: uiview) { } } but want use uilabel , how work around this? you use associatedtype constrained of type uiview . protocol a: class { associatedtype view: uiview func configure(view: view) } now in class b , since uilabel subclass of uiview , it's fine do: final class b: { init() {} func configure(view: uilabel) { ... } }

python - Read from two serial ports asynchronously -

i'd read 2 (or more) serial ports (/dev/ttyusb0 etc) @ same time in python on linux. want read complete lines each port (whichever has data) , process results in order received (without race conditions). simple example write lines single merged file. i assume way based on pyserial, can't quite figure out how it. pyserial has non-blocking reads using asyncio , using threads . asyncio marked experimental. assume there wouldn't race conditions if processing done in asyncio.protocol.data_received() . in case of threads, processing have protected mutex. perhaps can done not in pyserial. 2 serial ports can opened files , read when data available using select() . you try take values in order , memorise in variables: a = data1.read () b = data2.read () and after process in order: if len (a) != 0 or len (b ) != 0: process process b using method if 1 or both of value has data, process it

java - Difference between class declaration -

what's difference between declaring class inside of class , declaring class in separate file?. literally, nested classes added java 2 reasons: 1. source code clarity. 2. name-conflict reduction. java didn't need support doing this, totally doing programmers "solid" because i'm sure know how messy code can when you're in moment of all. to answer question, explicitly: difference there not difference, makes code easier read , end less name-conflict mistakes.
