The example file is Genewise(x, "TLR4"). See the below mentioned link. https://rdrr.io/cran/pubmed.mineR/man/Genewise.html and in R studio, I am running Genewise(Abstracts, "TLR4"), getabs(Abstracts, "acinetobacter") ,Give_Sentences_PMC(PMC4039032, "atherosclerosis") and help(pubmed.mineR). But nothing work. Does anyone use Pubmed.mineR. I am doing something wrong or is there any problem with pubmed.mineR. Please let me know.
