Hi,
Calling installed.packages() on a directory with only one package causes an
error if the priority argument is set to "NA":
> installed.packages(lib.loc = "/home/lhansen/R/libs", priority = "NA")
Error in mat[, "Package"] : incorrect number of dimensions
This seems like a classic dropping from matrix to vector bug. Maybe the code
should be mat[, "Package", drop=FALSE].
It works fine with other arguments:
> installed.packages(lib.loc = "/home/lhansen/R/libs", priority = NULL)
Package LibPath Version Priority Bundle Contains Depends
test "test" "/home/lhansen/R/libs" "1.0-0" NA NA NA NA
Imports Suggests OS_type Built
test NA NA NA "2.8.0"
and:
> installed.packages(lib.loc = "/home/lhansen/R/libs", priority = "high")
Package LibPath Version Priority Bundle Contains Depends Imports Suggests
OS_type Built
The documentation clearly states that "NA" is a valid argument value. It says:
To select all packages without an assigned priority use 'priority = "NA"'
