[R] x axis labelling

2014-07-01 Thread Michael Millar
Hi, I am new to R and am trying to create a graph with Time(24hr) along the x axis. Rather than start at 01.00, I wanted to start at 14.00. I tried to use the axis(side=1, at=c( )) function but it continues to put then in numeric order. Is there another way I can add labels to the x axis?

Did you add xaxt = n in the plot function? Try the following: plot(x,y, xaxt = n) axis(1, at = c(14, 20),labels = c(14h, 20h) ) 2014-07-01 12:41 GMT-05:00 Michael Millar michael88mil...@hotmail.co.uk: Hi, I am new to R and am trying to create a graph with Time(24hr) along the x axis.

Hi Dave, Thanks for your reply. I can't reproduce the last line of code your code. The ifelse argument throws back an error saying it was not used. A On Fri, Feb 1, 2013 at 10:56 PM, David Winsemius dwinsem...@comcast.netwrote: On Feb 1, 2013, at 9:30 AM, Alfredo Tello wrote: Hi Folks!

Hi Folks! I have a question regarding an issue on which I´ve read a few threads but can´t resolve -- Labelling every other tick mark on the x-axis using factors. Here´s an example: db-data.frame(date=as.factor(c(1:50)),var=rnorm(50))
