I'm trying to select a subset from character vector using the logical operator >, but get the following error
6356 85 SOL 1 25 1 38E6 6357 85 SOL 1 27 1 38E6 6910 95 SOL 1 25 1 38E6 7152 98 SOL 1 19 1 38E6 7153 98 SOL 1 22 2 38E6 7154 98 SOL 1 28 1 38E6 > ca11c93SOL1VIIa<-ca11c93SOL1[ca11c93SOL1$RECTAN>"32Z9",] Warning message: ">" not meaningful for factors in: Ops.factor(ca11c93SOL1$RECTAN, "32Z9") (note RECTAN is the name assigned to the 7 th column) Do these operators act on chacters vectors as opposed to numeric vectors and if so what are the rules for this?
