Hi, r-community,
This morning, I MET the following problem several times when I try to attach
the data set.
When I closed the current console and reopen the R console, the problem
disappear. BUt with the time passed on, the problem occurs again.
Can anyone help me with this?
attach(total)
The following object(s) are masked from total ( position 3 ) :
acid base cell_evalue cell_hit charged freq_cell freq_hypo freq_intra
gene_id gene_name hydrophobic hypo_evalue hypo_hit log_cell log_hypo
log_pfam num_cell num_genes operon_id outcome pfam_align pfam_evalue
pfam_per_id polar position target total_length
It appears you are attaching it multiple times, and never detaching it.
So the most recent one masks an earlier one.
This is a very easy error to make, which is one reason I always
discourage this kind of use of attach(). (There are other common errors
associated with it too. Just don't use it.)
