Inside the document I have several "setwd()" to collect the datasets I use. After I compile from the terminal using "R CMD Sweave myproj.Rnw", I receive the error: Error in

Hi, I'm working with Sweave and I have some trouble generating table. The R code is: print(xtable(myTable, caption ="", label="tab:myTab", digits=3), tabular.environment='tabular', floating=TRUE, caption.placement="top",size="\\scriptsize") and the resulting LaTeX table is: \begin{table}[ht] \begin{center} \caption{Principal

Hi, I use the lda function from the MASS package to classify some samples according to some chemical properties. If I run lda without cross validation all is ok but, if I run lda with cross validation, the R consol say: resLDA <- ldaRedOx <- lda(Activity ~ TRedOx[,1:6], CV=TRUE, data=dfDataRedOx, subset=train) predLDA <- predict(resLDA, newdata=dfDataRedOx[-train,])$class >

Hi, I need to export to LaTex the summary of a PCA. So: myPCA <- prcomp(myDF) mySummary <- summary(myPCA) # print(xtable(mySummary)) How can I export to LaTeX not all the summary but only the first nPCs?? Best Riccardo

Dear list, I have some .xls files that I need to read into R. I am able to do so using read.xls in the gdata package, however the helper functions sheetNames and sheetCount fail.

Hi, I'm working with support vector machine for the classification purpose, and I have a problem about the accuracy of prediction. I divided my data set in train (1/3 of enteire data set) and test (2/3 of data set) using the "sample" function. Each time I perform the svm model I obtain different result, according with the result of the "sample" function. I would like
