xYplot problem
Dear R community,
Since upgrading to R v.2.6.1 and re-installing package Hmisc (binary
for Mac OS X v.3.4-3), I have been getting a error when trying to
make xYplots:
>plotcv<-c(34.88, 41.51, 45.81, 51.05, 51.66)
>plotcv.se<-c(2.406551, 3.071291, 4.331407, 3.213873, 4.838150)
>month<-c(6, 7, 8, 9, 10)
>library(Hmisc)
>xYplot(Cbind(plotcv, plotcv + plotcv.se, plotcv - plotcv.se) ~
month)
Error in xyplot.formula(formula = Cbind(plotcv, plotcv...

need help for superpc package
...ompute.fullcv=TRUE, compute.preval=FALSE, n.components=3,
n.fold=10)
I used cross validation to estimate the optimal feature threshold and
choose only those features whose univariate coefficient exceeds the
threshold.
To choose the best threshold I plotted the cross-validation curves by
superpc.plotcv(cv.type="full').
I work with 55 features and 43 samples.
I noticed that by repeating the call of superpc.cv (with the same
argument values) and then plotting the curves by superpc.plotcv, the
curves change and sometimes the best threshold changes value. Please
note that I chose compute....
