expression pattern (heat map) of a list of probsets ids

Hello friends,

I have an array (GSE63706), how I can have expression pattern of a list of targets genes (probsets ids) during different phase of experiment please?

This can get you started, hopefully.

library(GEOquery)
gse = getGEO("GSE63706")[[1]] 
library(ComplexHeatmap)
sampleNames(gse)=pData(gse)$title
Heatmap(exprs(gse)[5000:5100,],cluster_columns = FALSE)

Thank you very much Sean,

Suppose that I have already downloaded GSE63706 and normalized that and I have a normalized text file now. and I have also a list of probesets (a text file of my interest probesets) in this array. I want to have a heat map showing the expression pattern of my interest probesets in this array, for example in this array I have 4 varieties and different tissues (rind and flesh) and phases (0,10,20,30,40 and 50 days after harvesting). heat maps showing the expression pattern of my probsets in varieties, tissues and phases I mean...when I entered above codes,

library(ComplexHeatmap)
Loading required package: grid
> sampleNames(gse)=pData(gse)$title
> Heatmap(exprs(gse)[5000:5100,],cluster_columns = FALSE)
Error in (function (x)  :
  REAL() can only be applied to a 'numeric', not a 'NULL'
Error in match(x, table, nomatch = 0L) :
  cannot pop the top-level viewport ('grid' and 'graphics' output mixed?)
Error: VECTOR_ELT() can only be applied to a 'list', not a 'integer'
Error in x$just :
  VECTOR_ELT() can only be applied to a 'list', not a 'character'
Error in valid.unit(x, units, recycle.data(data, FALSE, length(x), units)) :

From where you knew about my interest probesets please? I am just interested in expression pattern of those probesets

Help me more please

May you please help me to know expression pattern of my probesets based on varieties, tissues and phases?

You could try replacing:

Heatmap(.....)

with

library(gplots)
heatmap.2(exprs(gse)[5000:5100,])

I'm not sure why your Heatmap() call does not work.
