[Bioc-devel] 答复: handling data.frame namespace

[Alice Yue]

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

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
