R help - Jul 2018 - even display of unevenly spaced numbers on x/y coordinates

Dear all,

please would you advise on how I could make an even display of unevenly
spaced number on a graph in R. For example, considering the code below :

BREAKS = c(0, 0.1, 1, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, 300,
400, 500)

a <- seq(0,100,0.1)
b <- seq(0,1000,0.1)

plot(ecdf(a), col="red", xlim=c(0,100), main=NA, breaks=BREAKS)
plot(ecdf(b), col="green", xlim=c(0,100), add=T, breaks=BREAKS)

I would like to show on X axis (0, 0.1, 1 and 10) spaced in an equal/even
manner.

thanks !

bogdan

Isn't this what I showed you how to do in [1]?

Dear Jeff,

thank you for your prompt reply and kind help.

During our previous conversation, we worked on a different topic, namely
subsetting the dataframe before using ecdf() function in ggplot2.

Now, i would like to know, how I could evenly space on the x axis the
values (0, 0.01, 0.1, 1, 10). Thanks again, and happy weekend ;) !

Hi Bogdan,
There seem to be three problems. One is that if you want a logarithmic
x axis you shouldn't have a zero (or a negative number) in your data.
The second is that you have to ask for a logarithmic axis. The third
is that you have limited your x axis to less than the range of the
data in "b"::

plot(ecdf(b),xlim=c(0.1,1000),col="red",main=NA,log="x")
plot(ecdf(a),col="green",add=TRUE)
