string
It took me quite some time to understand the difference between sep and
collapse.
The examples in Phil Spector's book (2008) helped me to get it:
paste(c('X','Y'), 1:5, sep='_')
"X_1" "Y_2" "X_3" "Y_4" "X_5"
paste(c('X','Y'), 1:5, collapse='|') ## sep=" " by default
[1] "X 1|Y 2|X 3|Y 4|X 5"
paste(c('X','Y'), 1:5, sep='_', collapse='|')
[1] "X_1|Y_2|X_3|Y_4|X_5"

Ivan's advice is good, but understanding clearly what
"character string to separate the results" might mean is
a bit tricky!
Example:
cvec<- c("J","e"," ","m","'","a","p","p","e","l","l","e",
" ","B","e","n","o","i","t")
cstring<- paste(cvec,collapse="")
cstring
# [1] "Je m'appelle Benoit"
Now try it without the 'collapse=""'.
Hoping this helps,
Ted.

Hi, If I understand what you mean (no example...), see ?paste and the collpase argument Ivan Le 12/7/2010 16:11, Benoit Wastine a ?crit :
Hi, I'm running R 2.11 Does anyone know if it possible to transform one character vector to one character string ? Many thanks Benoit
