Hi,
I want to prohibit the automatic collapsing of degenerate array
indices:
str( array(1,dim=c(3,4,5,1,1)) )
num [1:3, 1:4, 1:5, 1, 1] 1 1 1 1 1 1 1 1 1 1 ...
str( array(1,dim=c(3,4,5,1,1))[2:3,1:3,4:5,,] )
num [1:2, 1:3, 1:2] 1 1 1 1 1 1 1 1 1 1 ...
The last command removed the degenerate indices. I don't want
that. What
can I do?
Use "drop=FALSE". See ?"[".
Thanks a lot for the fast help, Duncan and David! Also thanks for the
hint of how to get help for [. I tried ?[ which did not work.
Try instead ?'['
The quoting with "?" is also needed for other functions such as dyadic
math Ops and %in% as well as for some Control function such as 'if'
and 'break'.
