[R] Recall: Problem with sequence in loop

[Muhammad Rahiz]

I recall the above problem. It works. Just error on my part in the file 
output.

Here is the script that works.

-----
seq <- paste(seq(1914, 1916, by=1), "*.y", sep=".")

for (i in 1:3){
list <- list.files("~/ukcp09/txt/x.djf", seq[[i]])
file <- lapply(list, read.table)

mean <- (Reduce("+", file))

myfile1 <- paste(strsplit(seq[[i]], "\\.")[[1]][1], "sum.txt", sep=".")
write.table(mean, file=myfile1, row.names=FALSE, col.names=FALSE)
}
