R help - Apr 2009 - paste to collapse vector to string

Hi,

 

I'm trying to collapse a character vector to strings, but I am getting
unexpected behaviors in list context:

 

A <- "a"

B <- c("b","c")

xx <- list(A=A, B=B)

 lapply(xx, paste, collaplse=".")

$A

[1] "a ."

 

$B

[1] "b ." "c ."

 

paste(B, collapse=".")

[1] "b.c"  # this is what I want

paste(A, collapse=".")

[1] "a" # this is what I want

 

Why does the list context give me back vectors? Am I missing something?

 

Thanks,

 

Xiao-Jun
