Hi all,
Why subscripting a one column matrix drops one dimension?
x<- matrix(rnorm(100), ncol=1)
str(x)
num [1:100, 1] -0.413 -0.845 -1.625 -1.393 0.507 ...
str(x[20:30,])
num [1:11] -0.315 -0.693 -0.771 0.448 0.204 ...
str(x[20:30])
num [1:11] -0.315 -0.693 -0.771 0.448 0.204 ...
Try x[20:30,1,drop=FALSE]
cheers,
Rolf Turner
