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

?paste

collapse = T may be necessary.

Hi,
If I understand what you mean (no example...), see ?paste and the 
collpase argument

?gsub

Also look at the even more powerful gsubfn package. There is also the  
stringr package.

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.

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"
