Hello,
I am trying to plot two sets of boxplots together. These are estimates of two
experiments and seven factors.
The results of the two experiments I want to plot as boxplots stacked to each
other.
Therefore I plot first the results of the first experiment; and next with the
add option the second set of boxplots.
The boxplots are plotted at 'at = 1:7 - 0.15 for the first experiment and
at=1:7
+ 0.15 for the second.
I surpress plotting the tickmarks and labels succesfully for the first boxplot
with xaxt="n".
But for the second this does not work!
I want to plot the tickmarks and labels at position at=1:7, as below using the
axis function.
But with this code also tickmarks and labels are plotted at position
at=1:7+0.15.
boxplot(coefs ~ factor, data = temp,
boxwex = 0.25, at = 1:7 - 0.15,
subset = experiment == "first", col = "red",
xlab = "factor",xaxt="n",
ylab = "individual estimates")
boxplot(coefs ~ factor, data = temp, naxt="n",add = TRUE,
boxwex = 0.25, at = 1:7 + 0.15,
subset = experiment == "second", col = "green")
axis(at=1:7,side=1,c("fac1","fac2","fac3","fac4","fac5","fac6","fac7"))
legend(6,-0.5, c("experiment1", "experiment2"),
fill = c("red", "green"))
Does anyone know how I can surpress these labels for the second boxplot?
Thanks in advance,
Karin
