Figure 2. Content of text file (.txt) containing elements of interest that are to be extracted from the text of melanoma synoptic report. This file is read into memory by the line mycolnames<-read.table("./melcolnames.txt", sep="\n", stringsAsFactors = FALSE)$V1 in the R script. Each line of the file is used in line pattern <-paste0(mycolnames[i],"(.*)?\r\n") to form portion of a Regular Expression text pattern for data element extraction; the extraction is performed in the immediate following line element <-str_match (ms$finding_text, pattern)[,2].
