Dear helpeRs,
I am attempting to read in a series of csv files so I can bind them
into one large dataframe. I have written the following script:
test <- list.files(".", pattern = "csv") #lline 1
imp <- list() #line 2
for (i in 1:length(test)) { #line 3
imp[i] <- read.csv(test[i]) #line 4
} #line 5
works <- do.call(rbind, imp) #line 6
write.csv(works, "allmet.csv") #line 7
This script has an error at line 4. imp[i] contains only the value
of the first element of test[i]; in other words, every element of
imp[i] equals test[i] [1,1]. Otherwise, the script works. Could
someone please enlighten me as to the correct syntax for line 4?
Just use lapply instead of a loop, easier syntax.
imp <- lapply(test, read.csv)
do.call(rbind, imp)
