Example:
see_context <- function(word, data, context) {
dat <- data$strings
temp <- grep(paste("^", word, "$", sep=""), dat)
if(length(temp))
index <- lapply(temp, function(x) seq(max(0, x - context),
min(x + context, length(dat
sapply(index, function(x) paste(dat[x]
Dear list,
I have a general problem that I really don't know how to solve efficiently
in R. Lets say we have a sequence of things, like for instance a string of
words, that is stored in a file. We need all the words in a table format, so
therefore we create an id for the word, that links the word
2 matches
