Hi, I am plotting some expression values using plot() function as follows: x.chr.locations <- coords.chr[coords.chr.index] y.features <- as.numeric(X[feature.inds,7]) plot(x.chr.locations, y.features, pch=19) which gives me following error : Error in plot.window(...) : need finite 'xlim' values In addition: Warning messages: 1: In min(x) : no non-missing arguments to min; returning Inf 2: In max(x) : no non-missing arguments to max; returning -Inf 3: In min(x) : no non-missing arguments to min; returning Inf 4: In max(x) : no non-missing arguments to max; returning -Inf What could be the reason ? I have checked even by changing the values of X and Y parameters of the plot function. But no change. Please guide. Thanks, Tejal

However, without a reproducible example, it is impossible to tell. You can do: summary(x.chr.locations) to see if there are missing values. If so, you will want to remove those before plotting.
