RNA sequence analyzing data using R after DESeq2 (illumina)

1

Hello,
I aligned 3 group data and used DESeq2 in basespace.illumina.com/analyses/

Now I excel file of data after DESeq2.

can you guide how to continue in R and draw a plot Heatmap, and other graphs for the study of gene expression of 3 groups?
1- how upload excel with the below information in R?
2- when I use dds, there is an error. how I can remove the error? Thanks in advance

dds <- DESeq(dds)
Error in is(object, "DESeqDataSet") : object 'dds' not found
