Hello, I am using RStudio and have trouble finding out the problematic line in the presence of a bug. Could I view the line NUMBER which contains a bug? Is there any R editor able to do it? Thanks, Miao [[alternative HTML version deleted]]

One more comment: The utils::setBreakpoint() function should be updated to be able to set breakpoints in S7 methods, or a substitute function should be added to the S7 package. RStudio 2022.12.0+353 (not sure if that's the latest) also needs to be taught how to do that, since it doesn't seem to use setBreakpoint. Duncan Murdoch

Can I run R code straight from R src (.R) file instead of .rdb/.rdx? I of course tried simply unzipping tar.gz in the R_LIBS directory but R complains with "not a valid installed package". Real issue: I am very new to R and all, so this could be something basic. I'm trying to use ess-tracebug (Emacs front-end to trace/browser et al). It works great when I trace functions in .R

Hello, Let's say we have the following function: foo <- function(x) { line1 <- x line2 <- 0 line3 <- line1 + line2 return(line3) } And that we want to change the second line to be: line2 <- 2 How would you do that? The two ways I know of are either to use fix(foo) And change the function. Or to just write the function again. Is there

Hi all, I am in the middle of debugging which is stopped using "browser()"... in myfile.R at around line #25. I was then stuck in a big loop which I want to escape and stop the program at the line after the big loop. In the debugging mode, I used Browse[2]> setBreakpoint("myfile.R#38") I then typed "c" and "ENTER", thinking that it will continue

I have two pairs of related vectors x1,y1 and x2,y2 I wish to do a test for differences in means of x1 and y1, ditto x2 and y2. I am getting odd results. I am not sure I am using 'pt' properly... I have not included the raw vectors as they are long. I am interested if I am using R properly... > c(length(x1), length(y1), length(x2), length(y2)) [1] 3436 1619 2677 2378 First

Friends I need to get R reading from a fifo. I want it to block till there is some data in the fifo, consume what input it gets there, do some thing with it then loop back and block again. Very simple. Yes? No. The example in the documentation works OK.. zz <- fifo("foo-fifo", "w+") writeLines("abc", zz) print(readLines(zz))

It seems obvious to me that the empty string "" is length 0. cheers Worik [[alternative HTML version deleted]]

I have trouble with this: as.Date("Sep-1981", format="%b-%Y") Returns "NA" >From documentation for strftime '%b' Abbreviated month name in the current locale. (Also matches full name on input.) '%Y' Year with century. What am I doing wrong? cheers Worik [[alternative HTML version deleted]]

Is it possible to get a line number with an error report? I have a long script and an error: Error in `[.xts`(x, xsubset) : subscript out of bounds It would be very helpful, and save a lot of time, if there was some indication in the error message which line the error was. I can find it using binary search but that is a painful process. cheers Worik [[alternative HTML version deleted]]

Friends I am trying to format a number to a string so 2189.745 goes to "2,189.35" and 309283.929 goes to "309,283.93" I have tried to use formatC(X, big.mark=",",drop0trailing=FALSE, format="f") but it does not get the number of decimals correct. Specifying digits does not work as that is significant digits. I could use a switch statement switching on

Friends I have an xts that I wish to access. Browse[2]> DATA.ba[[p]]["2012-03-20 00:59:57","bid"] bid 2012-03-20 00:59:57 1.4993 So far so good. Now putting the index into a variable: Browse[2]> Time [1] "2012-03-20 00:59:57 NZDT" Browse[2]> DATA.ba[[p]][Time, "bid"] bid Where has it gone? Looking closer....

Friends I am new to R (and statistics) so am struggling a bit. Briefly... I am interested in getting the P-Value from cor(X) where X is a matrix. I have found cor.test. Verbosely... I have 4 vectors and can generate the corellation matrix... > cor(cbind(X1, X2, X3, X4)) X1 X2 X3 X4 X1 1.00000000 -0.06190365 -0.156972795 0.182547517 X2

Friends I am looking at Rcpp and I am a bit stuck on a simple matter. (I am calling R from c++, if there is a better way...) Given this simple example using the TTR package and the SMA function which returns a simple moving average.... Rcpp::NumericVector rv; for(int i = 0; i < 100; i++){ rv.push_back(rand()); } Rcpp::Environment TTR("package:TTR");

I have a large programme that after running half an hour or so fails with an error Error in x[value] <- NA : only 0's may be mixed with negative subscripts How can I find out where that error occurs? If I have to do a binary search using error messages it will take a long time! Is there some way I can generate a stack trace? cheers Worik [[alternative HTML version deleted]]
