Hi, I've posted the same question to the bio-sig-sequencing list (
https://stat.ethz.ch/pipermail/bioc-sig-
sequencing/2010-September/001564.html)
two days ago, but also interested to see if the main Bioconductor
group has
any input as follows:
I encountered some unusual behavior when concatenating multiple
DNAStringSet objects as follows:
library('Biostrings')
x <- DNAStringSet('ATA')
y <- DNAStringSet('GCG')
z <- DNAStringSet('AGA')
foo <- rep(list(x,y,z),1) # I was exploring to see if the length of
the list
made a difference (it doesn't)
do.call(c, foo) # creates a DNAStringSet
names(foo) <- c('x', 'y', 'z')
do.call(c, foo) # creates a DNAStringSet
names(foo) <- c('a', 'b', 'c')
do.call(c, foo) # creates a list instead, not a DNAStringSet
It seems that in the last case, a list is created rather than a
DNAStringSet. It seems that the operation in sensitive to the names()
of the list. Or is there an alternative means of concatenating
multiple DNAStringSets?
Thanks,
Andrew
