One way to extract specific lines from a .txt file based on predetermined variable values in R is as follows:
text <- readLines("file.txt")
values <- c("value1", "value2", "value3")
matches <- grep(paste(values, collapse = "|"), text)
output <- text[matches]
The output variable will contain all the lines from the .txt file that contain any of the predetermined values.
