I am facing the below error while working on the TM package with R. 

library("tm")
Loading required package: NLP
Warning messages:
1: package ‘tm’ was built under R version 3.4.2 
2: package ‘NLP’ was built under R version 3.4.1

corpus <- VCorpus(DataframeSource(data))

Error: all(!is.na(match(c("doc_id", "text"), names(x)))) is not TRUE

Have tried various ways like reinstalling the package, updating with new version of R but the error still persists. For the same data file the same code runs on another system with the same version of R.

I encountered this error using the BTM package also. As Eva notes, it may relate to your column headings (which must be doc_id and text, respectively). However, in my case it was because my doc_id values had become corrupted and were no longer unique. If the error persists, try examining your doc_id values to ensure they increment properly.
