Cex installation problem


Hi everyone,

I am unable to install cex packages for my Rstudio the error is cex is not available for R version 3.5.1.
if we can't download it for this version than how we can do the command character expansion in plots?



Please can you provide more information of what you have done and what is the error message exactly?

What you are describing can also mean that the url to download is not accessible due to bad internet or just a proxy to pass through to go online.

However, I do not find cex :package: on CRAN. :thinking:

There are cex options parameters for base R graphics though. (Example. Is this related to what you are looking for?


Thank you very much for your prompt reply.
I am running this command
plot(centes$agemean, centes$yi, pch=19, cex=size, xlab="Mean Age", ylab="Central Density", las=1, bty="l")
but i am getting this plot

while i need to weigh my scatter plot according to sample size, i have one generated by someone but i am not able to upload that file, she told me that this is the command i need to add cex command to add weight to plot. But my cex command is not working. Can you provide any help please? i hope the question is clear now.


when i am running the command with cex command i am getting this plot

but when i delete this my plot come like the one uploaded
but my command is not showing any error , just the plot becomes blank. I hope my question is not too stupid and it makes sense.


Ok, this is clearer and it is not at first an installation issue. it needs further investigations.

Could you please turn this into a self-contained reprex (short for reproducible example)? It will help us help you if we can be sure we're all working with/looking at the same stuff.


If you've never heard of a reprex before, you might want to start by reading the tidyverse.org help page. The reprex dos and don'ts are also useful.

What to do if you run into clipboard problems

If you run into problems with access to your clipboard, you can specify an outfile for the reprex, and then copy and paste the contents into the forum.

reprex::reprex(input = "fruits_stringdist.R", outfile = "fruits_stringdist.md")

For pointers specific to the community site, check out the reprex FAQ.

Thanks !
