R help - Jan 2013 - Custom axis with months name

Hello!

I have data.frame with column class POSIXct:

data[, 1] <- as.POSIXct(data[, 1], format = "%d.%m.%Y %H:%M")

I need to write custom axis for plot where can be ex.: January (mean
of january's temperature). List of month I get as table(months(data[,
1])). What is next step? 

Thanks.

Hello,

To get the months names you can try

format(data[,1], "%B")

As for the axis, see the help page ?axis. Argument 'labels'.


Hope this helps,
