[BioC] Error in plot.window(...) : need finite 'xlim' values

[T Joshi]

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
