indat	the data.frame whose numeric fields are to be considered
years	identifies the name of the "Year" field in the data.frame
empty	logical default=FALSE, determines whether columns which have no NA present are printed or not

year <- sort(rep(1990:1994,5))
columns <- c("year","Var1","Var2","Var3")
dat <- matrix(runif(100),nrow=25,ncol=4,dimnames=list(year,columns))
dat[trunc(100*runif(20))] <- NA
dat[,1] <- year
