Hi Michael,
Works if the DataFrame has columns:
library(IRanges)
DF1 <- DataFrame(aa=letters[1:4])
DF0 <- DF1[0]
Then:
> DF1
DataFrame with 4 rows and 1 column
aa
<character>
1 a
2 b
3 c
4 d
> DF0
DataFrame with 4 rows and 0 columns
> subset(DF1, c(FALSE, TRUE))
DataFrame with 2 rows and 1 column
aa
<character>
1 b
2 d
OK. But:
> subset(DF0, c(FALSE, TRUE))
Error in NSBS(i, x, exact = exact, upperBoundIsStrict = !allow.append) :
subscript is a logical vector with out-of-bounds TRUE values
This currently causes subset() to fail on a GRanges object with no
metadata cols.
Thanks,
H.
