[R] Error when calling residual.plots() on an ANOVA object
Dear *,
I have to perform an ANOVA analysis to study the effects on the
performance of some algorithmic components in the design of my
algorithm.
I have done a full factorial design for the following 5 factors (my
response variable is "best"):
$ model :'data.frame': 3360 obs. of 6 variables:
..$ best : num [1:3360] 0.108 0.573 0.625 1.057 0.451 ...
..$ comm.strat: Factor w/ 4 levels
"FC","HC","R",..: 1 1 1 1 1 1 1
1 1 1 ...
..$ migr.freq : Factor w/ 2 levels "d","s": 1 1 1 1 1 1 1
1 1 1 ...
..$ max.cpu : Ord.factor w/ 2 levels "4"<"8": 1 1 1
1 1 1 1 1 1
1 ...
..$ instance : Factor w/ 7 levels "kroA100","eil101",..:
1 1 1 1
1 1 1 1 1 1 ...
..$ max.iter : Ord.factor w/ 3 levels
"1000"<"3162"<..: 1 1 1 1 1
1 1 1 1 1 ...
I would like to plot the residuals for my 5 factors, but when I call
the function residual.plots(), only the first 3 plots (comm.strat,
migr.freq, max.cpu) are done and then I obtain an error:
> anova.ax3<-aov(best~(comm.strat+migr.freq+max.cpu+instance
+max.iter)^2,data=BestDF)

Error in Summary.factor(..., na.rm = na.rm) :
min not meaningful for factors
In addition: Warning message:
the condition has length > 1 and only the first element will be used
in: if (class(horiz) != "factor") {
>
I think that there is some issues when processing the "instance"
factor (the levels are names of instances).
Could somebody give me a hand to understand what is going on?
This is the script I use to make the analysis:
