This is workaround by defining the 'global variables' as NULL. Use it with caution.

### Fooling R CMD check
transition_group_id <- NULL
### Fooling R CMD check

setkey(aligtable,transition_group_id,align_origfilename)

To call in the statistician after the experiment is done may be no more than asking him to perform a post-mortem examination: he may be able to say what the experiment died of.

The combination of some data and an aching desire for an answer does not ensure that a reasonable answer can be extracted from a given body of data.

Onderwerp: [R] data.table and R package check

Hi,

using data.table in package code i.e

setkey(aligtable,transition_group_id,align_origfilename)
aligtable = aligtable[CJ(unique(transition_group_id),
unique(align_origfilename))]

When I do run R package check I got warnings such as:

convert2msExperiment: no visible binding for global variable
  'transition_group_id'

.... and more and more and MORE

I can't suppress those warnings by putting transition_group_id into quotes because this would break this code:

aligtable = aligtable[CJ(unique(transition_group_id),
unique(align_origfilename))]


Any alternatives?

regards
