Please suggest areas that I should troubleshoot. This command used to give me an answer and now it gives me an error.
> mean(no.genot,na.rm=T)

Error in tapply(x, by, sum, na.rm = TRUE) :

        arguments must have same length
I tried removing the na.rm=T)
> mean(no.genot)

Error in `names<-.default`(`*tmp*`, value = c("by.1", "by.0")) :

        attempt to set an attribute on NULL

The structure of my table is as follows.
> str(no.genot)

 table [, 1:467] 0.000 0.261 0.315 0.274 0.349 ...

Strangely enough
> mean(no.genot[1:467])

[1] 0.2426167

That seems to work.
