Instead I used labels like below

Re: [R] Special characters in cell names
Try:
ggplot(mydata, aes(x=W, y=`X/Y`)) + geom_violin(trim=FALSE)
Note the use of *backticks*, ``, not single quotes, ' ' . ** They are
different.**
So, yes, your data got read in correctly, presumably because "/" is
considered a character in your locale. It is not in mine. So my suggestion
was indeed irrelevant.

Re: [R] Special characters in cell names
Hi Bert,
I don't know what does "check.names" do here, but my commands look like
> mydata <- read.csv('r.3080..csv', header=T,row.names=1)
> head(mydata)
W AX/Y
P1 M 1.469734 0.004144405
P2M 20.584841 0.008010306
P3 M 53.519800 0.166034888
P4 M 42.308700 0.051545443
P5 M 99.236384 0.893037857
P6M 94.279504 0.856837525
So when I use
p <- ggplot(mydata, aes(x=W, y='X/Y')) + geom_violin(trim=FALSE)
The output is not correct. I don't see values (scale) on the y-axis.
Anyway, I fixed that with a label.

Mahmood

Re: [R] Special characters in cell names
I found your specification quite vague. What did you mean by a "data file" -- a data frame in R? -- a file in the file system? I may be completely wrong here, but another possibility is that you read your data into an R data.frame via, e.g. read.table() or read.csv(), but failed to specify the check.names = FALSE, argument. This would cause a column named "x/y" in your original table to be given the name "x.y" in R, as "x/y" is not a syntactically valid name. See ?make.names for details. As others have already said, enclosing non-syntactically valid names in back ticks usually works (maybe always works??). So for example: z<-data.frame (`a/b` = 1:5, y = 1:5, check.names = FALSE) plot(y ~ `a/b`, data = z) ## produces desired plot with correct label z ## yields: a/b y 1 1 1 2 2 2 3 3 3 4 4 4 5 5 5 Of course, ignore if this is all irrelevant.

Re: [R] Special characters in cell names
Unfortunately, using 'X/Y' doesn't work either. Instead I used labels like below P + scale_y_continuous(name="X/Y") Thanks for the suggestions.

Re: [R] Special characters in cell names
If no one comes up with a better suggestion: a. Change the column name to "Y" so that you get the plot you want b. Use axis labels and legend text to show the text that you want.

Any ideas for that? I haven't tried, but I'd expect back quotes would work: ggplot(mydata, aes(x=W, y=`X/Y`)) That's the normal way to quote a name in R.

Re: [R] Special characters in cell names
Use backquotes, `X/Y`, to specify a name, not double quotes. -Bill On Wed, Jun 23, 2021 at 11:58 AM Mahmood Naderan wrote: > Hi > I have a column in my data file which is "X/Y".

[R] Special characters in cell names
Hi I have a column in my data file which is "X/Y". With '/' I want to emphasize that values are the ratio of X over Y. Problem is that in the following command for a violin plot, I am not able to specify that '/' even with double quotes. p <- ggplot(mydata, aes(x=W, y="X/Y")) + geom_violin(trim=FALSE) However, if I change that column to "Y" and use p <- ggplot(mydata, aes(x=W, y=Y)) + geom_violin(trim=FALSE) Then the plot will be correctly shown. Any ideas for that?
