I wish to drop repeating text "BST" from the below 'dates' string: [1] "2005-04-01 BST" "2005-04-04 BST" "2005-04-05 BST" "2005-04-06 BST" "2005-04-07 BST" "2005-04-08 BST" "2005-04-11 BST" "2005-04-12 BST" "2005-04-13 BST" "2005-04-14 BST" "
You can use regular expressions but if your string is like you showed us, dates1 <-substr(dates, 1, 10)
2. I then wish to add this (cleaned-up) 'dates' string as the row names to a matrix (same length as 'dates' string)
rownames(mat) <- dates1 Regards Petr
