Dear R community. I have two problems with figures. First deals with short vector on the x-axis and the second with two-panel barchart. 1) For demonstration I create the following pseudo data for three years, 2001:2003. The indicated plot looks fine except for the number of tick marks on the x-axis. I get seq(2001,2003,0.5). I want three and only three tick marks to indicate we have measure once a year not two times each year. (Having year 2001.5 is not that nice anyway). I tried as.factor(2001:2003) but this did not do what I want. I have considered having no labels and plot the year with text(y=-b,x=(2001,2002,2003), (2001:2003) ) -b being some value less than 0. A simpler version is preferred. 2) For the second problem I want to use the same data but create a barchart with two bars (Group A and group B) for 2001, same two groups for 2002 and same two for 2003. Group A would have blue bars and Group B red bars. Would I use barchart() or panel.barchart()? Looking in help(barchart) I find that I need to define a formula. What would the x, y and g1 be in my case?
All help highly appreciated Thanks, Stefan demo1 <- matrix(nrow=3, ncol =2, log(c(7,3,2,4,5,6))/log(7) , dimnames =list(as.character(2001:2003), c("Group A","Group B")) ) windows() par(lab=c(3, 6,7) ,las=1 ) plot(x=(2001:2003), y=demo1[,1]*100,type = "l", lwd=3,ylim=c(0,100), xlab = "" , ylab="%") lines(x=(2001:2003), y=demo1[,2]*100, lwd=3, xlab = "Year" ) ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
