Convert R vector to string vector of 1 element [duplicate]
Im working with the programming language R now. I have a vector:
a <- c("aa", "bb", "cc")
And I want to paste these to a system command, I'm trying it this way now:
args <- paste(a, sep=" ")
system(paste("command",args, sep=" "))
But now I'm only getting the arguments aa, and I want the arguments aa, bb and cc...
Anyone knows what I'm doing wrong?
Solution 1:
Use the collapse argument to paste:
paste(a,collapse=" ")
[1] "aa bb cc"
