Re: [R] Concatenating two vectors into one
If you want to concatenate the *vectors*, you need 'c', which will
also coerce the elements to a common type.
If you want to concatenate the corresponding *elements* of the
vectors, you need 'paste', which will coerce them to character
strings.

Re: [R] Concatenating two vectors into one
Sorry,
I saw the word concatenate and dived in. Andrew Dolmans solution works fine.

It seems that "c(x,y)" is not correct:
z<-c(x,y)
z
[1] "A" "B" "C" "D" "E" "F" "1" "2" "3" "4" "5" "6"

Dear users,
a very simple question:
Given two vectors x and y
x<-as.character(c("A","B","C","D","E","F"))
y<-as.factor(c("1","2","3","4","5","6"))
i want to combine them into a single vector z as A1, B2, C3 and so on.
z<-x*y is not working, i tried several others function, but did not get
to
the solution.
Thanks for your help,
Henning

And a very simple solution! Use paste():
x<-as.character(c("A","B","C","D","E","F"))
y<-as.factor(c("1","2","3","4","5","6"))
paste(x,y)
# [1] "A 1" "B 2" "C 3" "D 4" "E 5" "F 6"
paste(x,y,sep="")
# [1] "A1" "B2" "C3" "D4" "E5" "F6"
Ted.
PS: 'x*y' will attempt to perform a numerical multiplication.
This cannot work for character vectors.

Re: [R] Concatenating two vectors into one
Something like this should work:
z<- paste(x,y, sep='')
