How to plot volcano plots without getting the not numeric error

#1

Hi,

I'm trying to create a volcano plot and keep getting the same error.

I ran the following code in RStudio...

EnhancedVolcano(res, lab = rownames(res), x = 'Log2foldchange', y = 'pvalue', xlim = c(-8,8), title = 'Macrophage', pCutoff = 10e-16, FCcutoff = 1.5, pointSize = 3.0, labSize = 3.0)

And received the following error...

Error in EnhancedVolcano(toptable = data.frame(results), x = "log2fc", : log2fc is not numeric!

I tried to downloading "datapasta" and received the following issues,

Warning in install.packages :

    Warning in install.packages :

not sure how to add the data file.

This is telling you that you have to install readr first, but regardless, you could still use dput() function without installing anything.
