This is a small subset of my data. plot(pair$MC~pair$Day, pch=c(19,24)[as.factor(Cookie)], xaxt="n", main='Paired t Test', xlab='Days in Field', ylab='Moisture Content (Percent)') Gives me the plot I need minus the x axis. Adding axis(1, at=0,15,30,45) or using a sequence of axis(1, at=seq(0,45,15)) gives me either x and y are different lengths or plot.new has not been called yet. Everything else is perfect. -- View this message in context: http://r.789695.n4.nabble.com/scatterplot-x-axis-specifications-tp4630952p4630961.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
