Files with unknown file names - r

Question

I am having a folder where I have a lot of csv files in it.
Can I read all of them, for example as zoo object without knowing the file name?
UPDATE
I tried that:
files <- list.files( "C://Users//ramid//Desktop//Files//" );
(na.omit(files))
for( i in files ) {
filePath <- gsub(" ","", paste("C://Users//ramid//Desktop//Files//",files[i],".csv"), fixed=TRUE)
cat(filePath)
df <- read.csv(gsub(" ","", filePath, fixed=TRUE), header = TRUE, sep = ";",stringsAsFactors=FALSE)
}
However I am getting an error:
Error in file(file, "rt") : cannot open the connection
In addition: Warning message:
In file(file, "rt") :
cannot open file 'C://Users//ramid//Desktop//Files//NA.csv': No such file or directory
I do not have any NA in my files list.

Answer 1

I'd use a combination of list.files and lapply:
list_of_files = list.files('.', pattern = '*csv', full.names = TRUE)
list_of_csv_contents = lapply(list_of_files, read.csv)
list_of_zoo = lapply(list_of_csv_contents, zoo)
Or wrap both the read.csv and zoo in one step:
read_into_zoo = function(path) {
contents = read.csv(path)
zoo_contents = zoo(contents)
return(zoo_contents)
}
list_of_zoo = lapply(list_of_files, read_into_zoo)
This strategy of storing things in lists/arrays/vectors/matrices and using apply style looping is a strategy that works very well in R.
