Hi Martin,
That... seemed to have done the trick!
No I didn't have it in before, not with the quotes on ".I".
Thank you so much!
Alice

主题: Re: [Bioc-devel] handling data.frame namespace
in your package NAMESPACE do you importFrom(data.table, ".I") ?

Hello there,
I am working to update the flowGraph package on Bioconductor and I keep
getting an error about a missing namespace for the following code (namely ".I"
for specifying the row in data.table):
dt <- data.table::as.data.table(vec)[ , list(list(.I)), by=vec]
a code a got from
(https://stackoverflow.com/questions/22993637/efficient-r-code-for-finding-indices-associated-with-unique-values-in-vector),
it's a faster version of getting the indices of each unique value in a vector.
I had the same problem when I was using ggplot (for column names of
data.frames), but in this case I don't know if there is a work around?
Thank you,
Alice
