Hi

I know this has been discussed already, but the answers I found do not solved my issue.

Here the code

R_code <- plot(CHD~genotype, data=peptide)

# Error in plot.window(...) : need finite 'xlim' values

In addition: Warning messages:

1: In xy.coords(x, y, xlabel, ylabel, log) : NAs introduced by coercion

2: In xy.coords(x, y, xlabel, ylabel, log) : NAs introduced by coercion

3: In min(x) : no non-missing arguments to min; returning Inf

4: In max(x) : no non-missing arguments to max; returning -Inf

5: In min(x) : no non-missing arguments to min; returning Inf

6: In max(x) : no non-missing arguments to max; returning -Inf

"CHD" and "genotype" are categorical variables. However, even when I try to run the same function with numerical variables (from another dataset) I get the same error message.

I have loaded the datased from a .csv

The only thing that these datasets have in commond is that they all come from csv files, but I can't figure out what is the problem and how I can fix it.

Any help is really appreciated.

THanks
