object 'countData' not found so you don't have any countData object loaded, it should be a matrix of counts created before running this code

Thanks Basti for reply ,

CountData <- read.csv('om_060_12.csv', header = TRUE, sep = ",")

I have added the count data and the headcount gives the result. still, The error is not solved.

CountData is different from countData, please check the names of the object you are calling in DESeqDataSetFromMatrix
