[R] customizing the axis (adding labels)

[Jörg Groß]

Hi,

I want to customize the x-axis.

I tried that:
par(bty="n", xaxt="n")
so that the x-axis is supressed.

then I tried to plot two variables and add a customized x-axis:
plot(x, y)
axis(1, at=c(1,2), labels=c("group1", "group2"))

but the axis is not added to the plot.

I don't understand why..
And how then can I customize the axis?

Would you provide reproducible code because form your example it looks
like you are trying to label a scatterplot with just two lables - this
is your boxplot from yesterday? If so look into the ?boxplot and it
will tell you some answers

No, what I want is to plot the mean for two different groups.
So that I get group 1 and 2 on the x-axis and also label it like that.

[stephen sefick]

j = c(5,6)
f = c(1,2)
plot(f,j, xaxt="n")

axis(1, at=c(1,2), labels=c("group1", "group2"))

the xaxt="n" needs to be inside of the plot command otherwise you can
never plot the x axis- I think.

Ah, ok, thanks!
Now it works fine.

Here a complete example of what I wanted to plot:

par(bty="n", mar=c(10, 10, 3, 3))
plot(c(1,2), c(50,60), ylim=c(40,70), xlim=c(0,3), xaxt="n")
dispbars(1,50,5)
dispbars(2,60,5)
axis(1, at=c(1,2), labels=c("group 1","group 2"))

Hi Jorg,
This is a wild guess, but are 1 and 2 anywhere on the x axis of your
plot? That is, if the plot axis runs from 5 to 10, you will see neither
your axis labels nor the tick marks where they are placed.
