I have created a galaxy tool, which get the gene expression data. I want to do some gene expression analysis on this data and display the summary of it. The output file data format which I saved is .tabular.

I do not know how to use this data in the same R code to do and display some statistics summary on it.

Thank you so much for your response,

Here is xml wrapper:

 <tool id="get_data" name="Get Study version="0.1.0">
    <description>Get a specific study</description>
     <command detect_errors="exit_code" interpreter="Rscript --vanilla">
        getData.R ${studyid} ${output}
        <param name="studyid" type="select" label="Study ID">
          <option value="SDY269">SDY269</option>
          <option value="SDY270">SDY270</option>
        <data name="output" format="tabular" label="${studyid}" />
    Obtain a study expression matrix.

and R code:

args = commandArgs(trailingOnly=TRUE) <- args[1]
out.file <- args[2]
sdy <- CreateConnection(
exprEset <- sdy$getGEMatrix(c("TIV_2008"))
expr <- exprs(exprEset)
probes <- rownames(expr)
saveExpr <- cbind(probes, expr)
colnames(saveExpr) <- c("ProbeID", colnames(expr))
write.table(saveExpr, file=out.file, sep="\t", quote=FALSE, 
              row.names=FALSE, col.names=TRUE) 

I want to display the some other information like: dim(), column names, number of samples and other information in the same page as text after getting the data.

Thanks again,
