I'm using R package 'pubmed.mineR' package which provide 'gene_atomization' for fetching genes from pubmed abstract. but 'readabs' function read only single text file.
file <- list.files(pattern = "txt$")
abs <- readabs(file)
this code show error can anyone help for reading multiple abstract text file
I also tried 'Corpus' function of 'tm' package, it is still not working
