[R] Merging matrices of different rows

[Steven Yen]

I'd like to cbind matrices of different number of rows, with missing values filled by "NA". I used dplyr. The following is obviously not working. Help appreciated.

> library(dplyr)
> a<-matrix(1:12,nrow=6); a
     [,1] [,2]
[1,]    1    7
[2,]    2    8
[3,]    3    9
[4,]    4   10
[5,]    5   11
[6,]    6   12
> b<-matrix(5:12,nrow=4); b
     [,1] [,2]
[1,]    5    9
[2,]    6   10
[3,]    7   11
[4,]    8   12
> cbind.fill(a,b)
Error in cbind.fill(a, b) : could not find function "cbind.fill"
