Hello,
That now seems to be a presentation problem. See this example:
x <- 0:30 + runif(124)
y <- cut(x, breaks = seq(0, 35, 5))
l <- levels(y)
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, ")"))
levels(y) <- l.new
str(y)
barplot(table(y))
Instead of 'y' use data.to.analyze$VegIndex and it should give what you
want.
Hope this helps,
Rui Barradas

Thank you! That has worked for me when creating graphs. In plyr I used the
script:
# Veg Index
data.to.analyze$VegIndex <- cut(data.to.analyze$Veg,
breaks=seq(0, 35, 5), include.lowest=TRUE)
VegIndex <- data.to.analyze$VegIndex
plot(VegIndex)
But the vegetation distances on the x-axis in the graph are showing up as:
[-5,0] (0,5] (5,10] (10,15] (15,20] (20,25] (25,30]
I am concerned these vegetation classes are not grouped probably and there
is overlap between the classes. It should read, preferably without brackets
or only one kind ():
(-5-0) (1-5) (6-10) (11-15) (16-20) (21-25) (26-30)
How do I fix this?
Please advise, Jean
