Thanks.
R_inferno is a good material for me. In this document, there is several
sections titled "string not the name". I try try to change
get(paste("a.", i, sep = ""))[i] <- i+50
to
assign(get(paste("a.", i, sep = ""))[i], i+50)
however, error message:
Error in assign(get(paste("a.", i, sep = ""))[i], i + 50) :
invalid first argument
I don't know why...

Hi there,
I hope to modify values in a vector or matrix in the following code:
for (i in 1:9) {
assign(paste("a.", i, sep = ""), 1:i)
get(paste("a.", i, sep = ""))[i] <- i+50
}
I get the following error message:
Error in get(paste("a.", i, sep = ""))[i] <- i + 50 :
target of assignment expands to non-language object
I have read the FAQ "How can I turn a string into a variable?", however,
I don't find a way to deal with:
get(paste("a.", i, sep = ""))[i] <- i+50
Any suggestions? Thanks in advance!
