multiple text or string searches
...cript but it is for only single searches at a time. how can i get multiple searches e.g "xyz","abc","pqr".....at a time and can save the results to an out file. script:: x<- "abc" z<-NULL;for (i in 1:1235){{if (as.integer(regexpr(pattern=x,as.character(abstracts_abc[i,2]), ignore.case=TRUE)) != 1) z<- c(z, i) }} temp<- z[1]; testfile<- abstracts_abc[temp,] for (i in 2:250){temp<- z[i]; testfile<- rbind(testfile,abstracts_abc[temp,])} Kind regards Ab Rauf Shah [[alternative HTML version deleted]]
