The box plot looks fine: the numbers 2, 3, and 4 appear on the x-axis and the boxes...

Hi, I am trying to plot the following data such that both variable y and z vs x. (ie two lines on a single plot). As the x variable is not numeric, how do I go about it? Appreciate if any expert could help. I know I use plot() follow by lines() to add another line to the plot. But my problem is i was unable to plot y vs x in the first place. x y z D9S1820

Has anyone had success with producing legends to a qplot graph such that the legend is placed on the bottom, under the abcissa rather than to the right hand side ? The following doesn't move the legend: library(ggplot2) qplot(mpg, wt, data=mtcars, colour=cyl, gpar(legend.position="bottom") ) I am using ggplot2_0.8.2. Thanks in advance, Avram

Hi, All, I am trying to use R to make the following type of boxplot while I couldn't find a way to do it. My dataset looks like X1 Y1 X2 Y2.... SPLIT. The split highlights my experiment details and both x and y are continuous numerical values. I need to plot y vs. x with split as legend and boxplot has to be used for all splits. May I ask how to get it? Currently available boxplot only

xyplot doesn't seem to want to label my x-axis with dates but instead puts the day-number for each date. begdate is the number of days since January 1, 1960 and was initially created by library(date) ... polls$begdate<-mdy.date(begmm,begdd,begyy) I create a new dataframe (pollstack) which includes begdate. In the process begdate seems to lose its date attribute so I redo it as: >

Dear all, I am making a barplot as following: barplot(c(1,2,3,5,2,3,1),names.arg=c("100","200","300","400","500","600","700"),xlab="diameter",ylab="flow",main="some title",space=0.1) I am also trying to add a probability density curve, however using lines(density(c(1,2,3,5,2,3,1))) does not give
