Thanks. But ... Still don't get it. Referring explicitly to the monthname column which had many entries across many years did not work. So taking your clue I created a new variable list of names of month
month.name<-list(c("Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec")) then issued this command plot(flow~factor(month),xlab="Month",ylab="Total Flow per Month", ylim=c(0,55000), xaxt="n", axis(1, at=1:12, labels=month.name)) which gave this error ERROR: 12, labels = month.name) Gregory A.

What am I doing wrong? > > plot(flow~factor(month),xlab="Month",ylab="Total Flow per Month", > ylim=c(0,55000), ticks.lab="monthname") ticks.lab is not a parameter to the plot.formula function. You don't say where you found it described, but I'd suggest you read your source more closely, or just use xaxt="n" in the plot call, and construct your own call to axis(), e.g. axis(1, at=1:12, labels=monthname).
