R: ggplot: Error: Unknown parameters: binwidth, bins, pad

geom_histogram() is no longer the most appropriate way to plot counts of discrete values.
As you've pre-calculated your frequency values use geom_col() instead, then all the errors will disappear.
library(ggplot2)
mydf <- data.frame(
Gene=c("APC","FAT4","XIRP2","TP53","CSMD3","BAI3","LRRK2","MACF1",
"TRIO","SETD2","AKAP9","CENPF","ERBB4","FBXW7","NF1","PDE4DIP",
"PTPRT","SPEN","ATM","FAT1","SDK1","SMG1","GLI3","HIF1A","ROS1",
"BRDT","CDH11","CNTRL","EP400","FN1","GNAS","LAMA1","PIK3CA",
"POLE","PRDM16","ROCK2","TRRAP","BRCA2","DCLK1","EVC2","LIFR",
"MAST4","NAV3"),
Freq=c(48,39,35,28,26,17,17,17,16,15,14,14,14,14,14,14,14,14,13,
13,13,13,12,12,12,11,11,11,11,11,11,11,11,11,11,11,11,10,10,10,
10,10,10), stringsAsFactors = FALSE)
mydf
ggplot(mydf, aes(x=Gene, y=Freq)) +
geom_col() +
scale_x_discrete(limits = mydf$Gene)
NB: also need to define your Gene column as not a factor and scale_x_discrete() to avoid alphabetical ordering of the x-axis.

I want to do a very simple histogram with ggplot2. I have the following MWE:
library(ggplot2) mydf <- data.frame( Gene=c("APC","FAT4","XIRP2","TP53","CSMD3","BAI3","LRRK2","MACF1", "TRIO","SETD2","AKAP9","CENPF","ERBB4","FBXW7","NF1","PDE4DIP", "PTPRT","SPEN","ATM","FAT1","SDK1","SMG1","GLI3","HIF1A","ROS1", "BRDT","CDH11","CNTRL","EP400","FN1","GNAS","LAMA1","PIK3CA", "POLE","PRDM16","ROCK2","TRRAP","BRCA2","DCLK1","EVC2","LIFR", "MAST4","NAV3"), Freq=c(48,39,35,28,26,17,17,17,16,15,14,14,14,14,14,14,14,14,13, 13,13,13,12,12,12,11,11,11,11,11,11,11,11,11,11,11,11,10,10,10, 10,10,10)) mydf ggplot(mydf, aes(x=Gene)) + geom_histogram(aes(y=Freq), stat="identity", binwidth=.5, alpha=.5, position="identity")
I have always used this simple code to produce this kind of histograms.
In fact, I have the plot for this particular example that I made some time ago...
However, now I run this exact same code, and I get the following error:
Error: Unknown parameters: binwidth, bins, pad
Why do I find this error now and not before, and what does it mean?
Thanks a lot!
