Here's some data (which should give you the error messages): # read in data data <- read.csv("https://dl.dropbox.com/u/13631687/data.csv", header = T, sep = ",") # first paste all data data1 <- paste(data[,1], collapse = "|") # second paste subsets of the data data2a <- paste(data[1:750,1], collapse = "|") data2b <- paste(data[751:1500,1], collapse = "|") # define the object to be searched text <- c("the first is Santa Fe Gold Corp", "the second is Starpharma Holdings") # match strapplyc(text, data1) strapplyc(text, data2a) strapplyc(text, data2b)
