There is a sample_annot function in cemitool package. I don't have an idea for sample annotation. My Sample barcode is TCGA... how is sample annotation for cell line or time point in R? Do you know this?

Sample annotation isn't required in CEMiTool. If you have no idea for what to use, you can just skip using it altogether, and just use the cemitool function as follows:
cem <- cemitool(expr)
where expr is your expression data with genes in the rows, samples in the columns, and gene names in the rownames.
Hope this helps,
Pedro
