[R] substring and paste character with a for loop

[Chris82]

Hello R users,

I have a little problem with a for loop.
Below there is an simple example of my problem.

I want to delet the commas in the character string. Fore this reason I
create a for loop to unpick the string and rebuild him without the commas.
The problem is, that "paste" does not work in the loop as I expected.

text <- "aaa,bbb,ccc,ddd"

characterseq <- seq(1,15,4)

for (i in characterseq ){
m <- paste(substring(text,i,i+2),sep = "")
}

> m
[1] "ddd"


m should be "aaabbbcccddd" and not just "ddd"



with best regards

Chris
