I have a serie of vectors with different lengths within the R environment, for example:
> s_aleat_0
[1] "12M08393" "12M08427" "12M08412" "12M08441" "12M08436" "12M08444" "12M08443" "12M08387"
> s_aleat_1
[1] "12M08405" "12M08389" "12M08439" "12M08406" "12M08397" "12M08402"
> s_aleat_2
[1] "12M08422" "12M08441" "12M08410" "12M08391" "12M08396" "12M08420" "12M08409"
And I want call them by pattern into another funtion (rbind his character strings to join the initial vectors in a bigger one) like that:
samples<-ls(pattern = "s_aleat_")
unique(c(rbind(samples)))
[1] "12M08393" "12M08405" "12M08422" "12M08427" "12M08389" "12M08441" "12M08412" "12M08439" "12M08410"
[10] "12M08406" "12M08391" "12M08436" "12M08397" "12M08396" "12M08444" "12M08402" "12M08420" "12M08443"
[19] "12M08409" "12M08387"
But when I put 'samples' inside rbind it doesn't recognize the vectors, if not the text obtained with ls function as I show below:
c(rbind(samples))
[1] "s_aleat_0" "s_aleat_1" "s_aleat_2" "s_aleat_4" "s_aleat_5"
How I could fixed it?
You can collect all the vectors in a list using mget and append NA's for vector with shorter length to create a matrix where each vector is a column.
s_aleat_0 <- c("12M08393","12M08427","12M08412","12M08441","12M08436","12M08444","12M08443","12M08387")
s_aleat_1 <- c("12M08405", "12M08389", "12M08439", "12M08406", "12M08397" ,"12M08402")
s_aleat_2 <- c( "12M08422", "12M08441", "12M08410" ,"12M08391", "12M08396", "12M08420", "12M08409")
tmp <- mget(ls(pattern = "s_aleat_"))
result <- sapply(tmp, `[`, 1:max(lengths(tmp)))
# s_aleat_0 s_aleat_1 s_aleat_2
#[1,] "12M08393" "12M08405" "12M08422"
#[2,] "12M08427" "12M08389" "12M08441"
#[3,] "12M08412" "12M08439" "12M08410"
#[4,] "12M08441" "12M08406" "12M08391"
#[5,] "12M08436" "12M08397" "12M08396"
#[6,] "12M08444" "12M08402" "12M08420"
#[7,] "12M08443" NA "12M08409"
#[8,] "12M08387" NA NA
