Creating vegetation distance groups from one column
Hello, My example with 'x' was just that, an example. Inline. Em 06-10-2012 00:03, Jhope escreveu:
Hi, I have tried the script posted but received the following errors. I hope I copied it correctly. I'm sorry but I don't know how to alter the script myself. Please advise, Jean
x <- 0:30 + runif(124) data.to.analyze$VegIndex <- cut(x, breaks = seq(0, 35, 5))
Error in `$<-.data.frame`(`*tmp*`, "VegIndex", value = c(1L, 1L, 1L, 1L, : replacement has 124 rows, data has 123
Use cut(data.to.analize$VegIndex, breaks = seq(0, 35, 5))
l <- levels(data.to.analyze$VegIndex)
l1 <- sub("\\]", ")", l[1])
l2 <- as.numeric(sub("\\(([[:digit:]]+),.*", "\\1", l[-1])) + 1
l3 <- sub(".*,([[:digit:]]+).*", "\\1", l[-1])
l.new <- c(l1, paste0("(",l2,",",l3, ")"))
Error: could not find function "paste0"
paste0 was introduced with R 2.15.0, update your version of R and in the mean time use paste(...etc..., sep = "") Rui Barradas
