Dear Users,
I have a little problem with user-defined function. I would like to remove
columns from a data frame using a user-defined function but i am getting a
"Error in ad[, -12] : incorrect number of dimensions error. The
"ad<-ad[,-12] and similar commands work from R console but i couldnt make
them run from my function. The function and the type imformation of one of my
obtained data objects is below.
Thanks in advance for your tips and helpful answers,
Levent TERLEMEZ.
Error:
Error in ad[, -12] : incorrect number of dimensions
My Function:
function (dyolu,dadi,dsayi)
{
for(i in 1:dsayi)
{
ad<-paste(dadi,i,sep="")
yol<-paste(dyolu,dadi,i,".csv",sep="")
print(ad)
print(yol)
assign(eval(substitute(ad)), read.csv(yol,sep=";",dec=",",header=T),
envir = globalenv())
ad<-ad[,-12]> Here I would like to remove some
columns but i even cant remove one. I tried all the suggestion on internet
forums.
#dat[ , -which(names(dat) %in% c("z","u"))]
}
}
dyolu: The string type variable containing the path of the csv files that will
be read.
dadi: The string type variable containing the name of csv files that will be
read.
dsayi: The numeri type variabe containing the number of files that will be read.
