I write a function to get the frequency and prop of a variable.
freq-function(x,digits=3)
{naa-is.na(x)
nas-sum(naa)
if (any(naa))
x-x[!naa]
n-length(x)
ta-table(x)
prop-prop.table(ta)*100
res-rbind(ta,prop)
rownames(res)-c(Freq,Prop)
cat(Missing value(s) are,nas,.\n)
cat(Valid case(s) are,n,.\n)
See ?sprintf
#e.g. Replace your prop line with:
prop-sprintf(%.2f%%, prop.table(ta)*100)
