I have the following little scrip to create a df of summary stats. I'm
having problems obtaining the # of unique values
unique=sapply(myData, function (x)
length(unique(x), replace = TRUE))
I just looked up the usage on `length` and do not see any possibility of
using a "replace" parameter. It's also unclear what sort of data object
`myData` might be. (And you might consider using column names other than
the names of R functions.)

Can I do that, or am I using the wrong R function?
summary.stats <- data.frame(mean=sapply(myData, mean, na.rm=TRUE),
sd=sapply(myData, sd, na.rm=TRUE),
min=sapply(myData, min, na.rm=TRUE),
max=sapply(myData, max, na.rm=TRUE),
median=sapply(myData, median, na.rm=TRUE),
length=sapply(myData, length),
unique=sapply(myData, function (x)
length(unique(x), replace = TRUE))
miss.val=sapply(myData, function(y)
sum(length(which(is.na(y))))))
