Hello,
See the difference.
a <- b <- c("A", "A", "B", "B", "C", "A", &quo
. Sorry one more query for one of my datasets which has NAs
(missing genotypes). Is there any way in which I can count NAs?
Many thanks!
Sarah

Your question is a little vague. Do you just want to know how often z falls
in one the three classes? If so, you could either code an indicator variable
(e.g. z.cat) that expresses the three categories and then do table(z.cat).
Alternatively, you could just do
sum(z>0&z<1000)
sum(z>1&z<3000)

You can use "cut" to create a new vector of labels and tabulate the result.
Options control closed/open endpoints (see ?cut):

hi,
i want to use the function table to build a table not of frequence
(number of time the vareable is repeated in a list or a data
frame!!) but in function of classes
I don t find a clear explnation in examples of ?table !!!
example
You need to create a factor that indicates which group the values in 'z' belong
to. The easiest way to do that based on your situation is to use the 'cut'
function to construct the factor, and then call 'table' using the result
created by 'cut'. See ?cut and ?factor
