Should the deparse.level=2 argument to cbind
and rbind be abandoned? It is minimally documented,
not used in any CRAN package, and causes some problems.
Bill,
This code has been touched by Brian quite recently. Try again with a
current r-devel checkout. (Specifically, later than r51007).
-p
E.g.,
(a) If a matrix input has row names but not column names
cbind(deparse.level=2,...) stops.
m<-matrix(11:14,nrow=2,ncol=2,dimnames=list(Row=c("R1","R2"),Col=charact
er()))
cbind(m, 101:102, deparse.level=2)
Error in cbind(m, 101:102, deparse.level = 2) :
SET_STRING_ELT() can only be applied to a 'character vector', not a
'NULL'
(b) If no argument is tagged then deparse.level=2
makes no column names, while deparse.level=1 makes
names for for the simple cases (where the argument
is a name):
x<-1:3
cbind(x, 11:13, deparse.level=1)
x
[1,] 1 11
[2,] 2 12
[3,] 3 13
cbind(x, 11:13, deparse.level=2)
[,1] [,2]
[1,] 1 11
[2,] 2 12
[3,] 3 13
(If one argument is tagged, teens=11:13, then
deparse.level=2 will name columns that
deparse.level=1 will not, like x+1, which I
think is the intended behavior.)
