when plot in log="x", and the data has a point with negative x such as
(-1,10000), and when the y for this x is the max of all y's in the data set,
the
y scale looks wrong.
p<-cbind(c(-1,10,100,1000),c(100000,1,2,3))
plot(p,log="x")
The data point (-1,100000), not just the x value of it, should be discarded.
Comment on gsub() and sub():
it is illogical to use \ to escape another \ which is for escaping other
characters such as gsub('\\([sS]\\),'\\1', a, extended=F). It should
only use \
to escape \ which is literal backslash. Also it should default to extended=F.
The above gsub() should read: gsub('\([sS\)','\1', a).
Thank you all for the great work!
