Could not find function 'estimateDispersion' error

[kasutubh]

Hi..
I'm running DESeq (2.11) on R (2.25.2) on windows 7 . I'm getting following error,
Error: could not find function "estimateDispersion"
Do I need to update anything or what am I doing wrong here?
Thanks!

Try this when stuck on a command in R:

?estimateDispersion
??estimateDispersion

The command is estimateDispersions. But the '??' should give you a pointer in the right direction by listing all possible commands matching your query.

Hi Bruce,
I'm still unable to understand why it can't find the function. I tried to update all the bioconductor packages..but the error remains.

"estimateDispersions" not "estimateDispersion"

You are missing an "s"
