Dan,
I am attempting to write a function to count the number of non-missing
values of each column in a data frame using the sapply function. I have the
following code which is receiving the error message below.
n.valid-sapply(data1,sum(!is.na))
Error in !is.na : invalid argument type
Ultimately, I would like for this to be 1 conponent in a larger function
that will produce PROC CONTENTS style output. Something like...
data1.contents-data.frame(Variable=names(data1),
Class=sapply(data1,class),
n.valid=sapply(data1,sum(!is.na)),
n.miss=sapply(data1,sum(is.na)))

Mike,
Small, reproducible examples are always useful for the rest of the us.
x - c(0, NA, NaN, 1 , 10, 20, 21, Inf)
x[!is.na(x) x =1 x= 20]
Is that what you're looking for?

Hello,
Although on the surface a simple request,

Just read ?formula, where it says:
There are two special interpretations of ‘.’ in a formula. The
usual one is in the context of a ‘data’ argument of model fitting
functions and means ‘all columns not otherwise in the formula’:

Everyone is free to create as they please. My opinion is that between
this list and stackexchange (as Tal pointed out), that there isn't
a market for such a thing.

Maybe try calling with the 'short directory name' notation,
I forget what that's called in Windows.
