Hello John, Thanks for your fast answer. I will try to be clearer and more detailed this time. At the moment I am importing a dataframe like below as a '.csv file'. I want to generate a boxplot for M and F values grouped by X whereby boxplots for M and F should be above or very close to each other. Please see attachment for example figure. Till now I have tried a code that looks like the one below the frame (I found it in the graph help of R for boxes close to each other):
X M F
Exp1 -90.0273224 -77.66531714
Exp1 -73.33333333 -96.36363636
Exp1 -98.24561404 -91.57848325
Exp1 -65.2173913 -59.18367347
Exp1 -98.7654321 -92.42424242
Exp1 -96.42857143 -89.25925926
Exp2 -84.61538462 -47.36842105
Exp2 -43.63636364 -22.37762238
Exp2 -47.5 -33.33333333
Exp2 -55.49450549 -66.66666667
>boxplot(
formula = F~Strain,
data = pain,
boxwex = 0.25,
at = 1:38 - 0.1,
subset =supp== "F",
col = "red",
xlab = "Strain",
ylab = " F"
)
boxplot(
formula = M~Strain,
data = pain,
boxwex = 0.25,
at = 1:38 + 0.1,
subset =supp== "M",
col = "orange",
add = TRUE )
...but I did cannot find anywhere what supp means and R cannot read it.
I hope this is explained ok. Any kind of answer would help!
Best
Mirjam

PLEASE do read the posting guide http://www.R-project.org/posting-guide.html
and provide commented, minimal, self-contained, reproducible code.
At a rough guess you may want to have a look at the mfrow in ?par but without
some sample data and a bit more information about what you need it is difficult
to suggest more.
By the way dput (see ?dput) is a handy way to supply a sample data set here.
