Help for string opeation

[Takatsugu Kobayashi-2]

Hi R users,

I appreciate if you could give me some hint/help on this string operation.

Suppose I have a list of string objects in varying sizes like

[[1]]
[1] "A" [2] "B" [3] "C"

[[2]]
[1] "D" [2] "E"

[[3]]
[1] "F"

Then I would like to create a vector that contains all elements like

[1] "A" "B" "C" "D" "E" "F"

I tried do.call + rbind but no luck yet.

Is there a function to do this operation or should I use append in the loop?

Thanks in advance!

Taka

Hello,

Does 'unlist' function do what you are asking about?

Regards.

Hi,

You could use "do.call" :
 a1<-c("A","B","C")
 a2<-c("D","E")
 a3<-"F"

 mylist<-list(a1,a2,a3)


 do.call("c",mylist)
[1] "A" "B" "C" "D" "E" "F"

A.K.
