Thanks Jim, maybe now I can start learning.
Here is a run of my trying to learn:
xvalue<-c(5.2,1.3,9.7,2.8,8.1,4.7,6.6,7.4)
yvalue<-c(9,3,4,7,2,5,3,6)
plot(xvalue,yvalue)
axis(1,at=NULL,labels=1/xvalue,digits=5)
Error in axis(1, at = NULL, labels = 1/xvalue, digits = 5) :
'labels' is supplied and not 'at'
In addition: Warning message:
In axis(1, at = NULL, labels = 1/xvalue, digits = 5) :
"digits" is not a graphical parameter
Why can't R automatically compute the spacing when I use the formula?
How can I specify n-digits or width instead of round or nothing?
Hi Hurr,
Let's see, suppose I answered your message like this:
answer1<-NULL
You would be in the same position as the axis function. You have to tell
the axis function where the labels are to be placed, or it can't place
them there. Now for your second question. Suppose my answer was
something like this:
answer2<-"wpsovmeksjhfhtieur" # language = Magungian
You might well respond that you don't understand Magungian. The argument
"digits" doesn't tell the axis function anything useful. If you want
labels with a certain number of digits, create them before you call the
axis function:
mylabels<-round(1/xvalue,digits=5)
The round function understands Magungian.
Jim
