Newbie with R
Hello,
I would like to test some learning algorithms (C5.0, or C4.5) using decision trees or neural network.
I didn't find anything in the R documentation for functions to apply on datasets (well, English is not my mother tongue and I have some problems to understand some functions descriptions). Does anybody know where I can find anything about that ?
Thank you very much,
Thomas

more than one time R (Win2000) and let run the process at one
task and work interactive normal with the other.......(but this is
perhaps dangeorous , cause of same .RData file) ?
while(1) {
queryTrack()

Correlation with small N
Hello r-proffessionals,
this is not a special R-Question, but have anybody
a good reason for nonstatistican's why the interpretation of correlations
with cases under 20-30 are dangerous !?
...i have got problems explain this without formula's and perhaps anybody
know a realworld example what point this problem !?
thanks for any suggestion or url/doc etc.
