Hi, I want to correlate two matrices of data. First matrix is metabolomic data with 8 biological replicates and 51 metabolites. Second matrix is the transcriptomic data with 8 replicates and 64 transcripts.

Metabolomic data

ID	A	A	A	A	B	B	B	B
1	1489	1285	478	125	148	125	128	489
2	12145	25	265	4548	8926	49526	7565	1558

...... and 50 more rows like this

Transcriptomic data

ID	A	A	A	A	B	B	B	B
1	14811	128555	478255	125889	148358	125248	12896	489355
2	12145245	88825	555265	4522548	8444926	46669526	7444565	7851558

...... and 64 more rows like this

How should I organize the input file? what is the code to run in R?

Thanks

Maria

Hi,

As you are not providing any code that you have tested nor name any packages that you have looked at it is hard to see that this is directly related to bioconductor. For a general description on how to generate a heatmap have a look at https://www.r-bloggers.com/how-to-make-a-simple-heatmap-in-ggplot2/
