[R] overplot() examples fail (package:gplots)

[Michael Kubovy]

require(gplots)
data(rtPCR)

overplot( RQ ~ Conc..ug.ml. | Test.Substance,
	data=rtPCR,
	subset=Detector=="ProbeType 7" & Conc..ug.ml. > 0,
	same.scale=TRUE, log="xy", f=3/4,
	main="Detector=ProbeType 7",
	xlab="Concentration (ug/ml)",
	ylab="Relative Gene Quantification"
)

# Error in lowess.default(mf[[-response]], mf[[response]], f = f,  
iter = iter,  :
# 	'x' is empty
# In addition: Warning messages:
# 1: no non-missing arguments to min; returning Inf
# 2: no non-missing arguments to max; returning -Inf

**************************************
# The second example fails as well, but with:
# Error in plot.window(xlim, ylim, log, asp, ...) :
# 	need finite 'ylim' values
# In addition: Warning messages:
# 1: no non-missing arguments to min; returning Inf
# 2: no non-missing arguments to max; returning -Inf
