Hello !!
I have this problem:
A matrix on True/False
and as many numerical vectors as columns,
but of different length. What I 'd like to get is this:
set.seed(12)
> dat <- as.data.frame(matrix(as.logical(sample(T:F, 30, T)),5,6))
> colnames(dat) <- letters[1:6]
> rownames(dat) <- paste(letters[1:5],1:5, sep="")
> dat
a b c d e f
a1 TRUE TRUE TRUE TRUE TRUE TRUE
b2 FALSE TRUE FALSE TRUE FALSE FALSE
c3 FALSE FALSE TRUE FALSE TRUE TRUE
d4 TRUE TRUE TRUE FALSE FALSE TRUE
e5 TRUE TRUE TRUE TRUE TRUE FALSE
>
> v1 <- c(1:3)
> names(v1) <- c("a1", "d4", "e5")
> v2 <- c(1:4)
> names(v2) <- c( "a1","b2", "c3","e5")
>
v1
a1 d4 e5
1 2 3
> v2
a1 b2 c3 e5
1 2 3 4
>
Desirable Output
dat
a b c d e f
a1 1 1 .....
b2 NA 2 .....
c3 NA NA
d4 2 3
e5 3 4 ......
Any suggestion ,
Thank you
Anna
