I'm having trouble getting the DEseqDataSetFromMatrix function to work. When I try to call it, I get this error:

Error in DEseqDataSetFromMatrix(countData = countdata, colData = coldata,  : 
  could not find function "DEseqDataSetFromMatrix"

When I try to download it, I get:

Warning message:
package ‘DEseqDataSetFromMatrix’ is not available (for R version 3.5.1)

I need this function for a homework for one of my classes. How do I get this to work? Thanks!

Capitalization matters in R. It is "DESeq..." You can use <tab> to autocomplete, if you don't want to spell out long function names.

> Sqrt
Error: object 'Sqrt' not found
> sqrt
function (x)  .Primitive("sqrt")

That's because the function is "DESeqDataSetFromMatrix".. The 'S' in "DESeq" is capitalized. R is case sensitive.
