Re: [R] Problem with loop in folders

Hi, I am sorry if I am misunderstanding what you are trying to do here, but can you simplify it this way? (unfortualtely, this is untested since I dont have a suitable set of files and a directory structure to test against) dbifiles <- list.files(pattern="*.dbi",recursive=TRUE) csvfiles <-

Re: [R] Problem with loop in folders

I suspect much if not all of your trouble would be eliminated by using file.path() instead of paste0(). https://www.rdocumentation.org/packages/base/versions/3.6.2/topics/file.path (Also check your file name - you probably want a . between name and csv, so using paste(name, "csv", sep = ".")

What package is "read.dbf" from? What error message/behavior did you see? Should it be: path<-setwd(paste0("inpath/",folder)) ## did you forget the "/" ? Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking things into it." -- Opus (aka Berkeley

[R] problem in loop using windows executable

Dear all, I am trying to develop a R script that basically uses a loop that includes 5 main steps: (1) it runs a windows executable file outside R that requires a set of *.txt files using the shell function (Note: I have tried system and system(shhQuote()) and the problem remains), (2) it imports

[R] Problem with loop, matrix and data frame

Hi all, I'm sorry, maybe the solution in my problem is easy, but i am still new to R, and any help here is appreciated! I want to create a data frame, or a matrix in which the output of each loop will be stored. Here is the program n-c(10,8,7,5) n_goal-c(8,9,9,4) w-c(0.1,0.1,0.1,0.1)

Re: [R] Problem with loop, matrix and data frame

You reused 'i' in the inner 'for' loop. This looks like it give the correct answer: n-c(10,8,7,5) n_goal-c(8,9,9,4) w-c(0.1,0.1,0.1,0.1) matrix-mat.or.vec(6,4) FI-function(n_t) { + (((n_goal[1]-n[1]+W[1]-f[1]+n_t[1])^2)+((n_goal[2]-n[2]+W[2]-f[2]+n_t[2]-n_t[1])^2)+ +

[R] Problem with loop

Hi, I try to build a loop difficultly. I have in a folder called Matrices several files (.csv) called Mat2002273, Mat2002274 to Mat2002361. I want to calculate for each file the mean of the column called Pixelvalues. I try this code but as result, I have this message: Mat2002273 not found

Re: [R] Problem with loop

You never create a variable called Mat2002273 or Mat2002361 so you can't ask R to loop over all the values between them. If I were you, I'd code something like this: lf - list.files() # PUT IN SOME CODE TO REMOVE FILES YOU DON'T WANT TO USE pv - vector(numeric, length(lf)) for(i in lf) pv[i]

Re: [R] problem in loop

I'm not too familiar with geese but it looks like the summary(fit)$correlation would be a dataframe. Maybe try getting the first (or whatever row you're interested in): ... corr_gee-summary(fit)$correlation[1,1] se_corrgee-summary(fit)$correlation[1,2] est[i,]-c(corr_gee, se_corrgee) ... Scott

Dear unbekannt; The construction that would append a number to a numeric vector would be: vec - c(vec , number) You can create an empty vector with vec - c() or vec - NULL -- David Winsemius On Apr 12, 2009, at 2:10 PM, unbekannt wrote: Dear all, I am a newbie to R and practising at
