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 <- gsub
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 = ".") woul
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 "/" ?

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)+
+
((n_goal[3]-n
Hi,
Thank Michael for your help.

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)
thank you so much!
this solved my problem

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
