Thanks,
The 'droplevels' statement works.

yuen does not work when there unused levels in the factors given to it.

>  yuen(GoalsGame ~ League, tr=0.2, data = SpainGer)
Call:
yuen(formula = GoalsGame ~ League, data = SpainGer, tr = 0.2)

Test statistic: NaN (df = NA), p-value = NA

Trimmed mean difference:  NaN
95 percent confidence interval:
NaN NaN

Re: [R] yuen function of the WRS2 package

2016-08-30 Thread Bert Gunter 
James:

To be clear, I know nothing about this package, but the following may
be helpful for those who do:

1. What exacty was the error message that you received? Or was it a
warning? "cannot read" may be too vague to allow others to respond.

2. ?maintainer to find the package maintainer. It may be necessary to
contact them directly with the problem.

Cheers,
Bert

[R] yuen function of the WRS2 package

2016-08-30 Thread James Henson 
Greetings R community,
Here is a small but perplexing problem with the ‘yuen’ function in the
‘WRS2’ package.
I begin with the ‘eurosoccer’ data frame from the ‘WRS2’ package.
Then make a subset that contains only two Leagues Spain and Germany
(subset data frame is ‘SpainGer’).   The ‘yuen’ function cannot read
the data in subset data frame ‘SpainGer’.  My code is below.
Thanks you for your help.
James F. Henson


# Examples from 'Robust Statistical Methods on R Using the WRS2 Package’
# Robust t-test, and ANOVA (pages5-13)
library(WRS2)
data("eurosoccer")
class(eurosoccer)
print(eurosoccer)
library("digest")
library("DT")
datatable(eurosoccer)
str(eurosoccer)
# make a subset with only Spain and Germany
SpainGer <- subset (eurosoccer, subset = League =="Spain" | League == "Germany")
print(SpainGer)
class(SpainGer)
str(SpainGer)
# The 'yuen' function can not read the data in the subset data.frame "SpainGer"
yuen(GoalsGame ~ League, tr=0.2, data = SpainGer)
# the 'yuen' function works on the orginioal data.frame
yuen(GoalsGame ~ League, tr=0.2, data = eurosoccer)
# the 'aov' function reads the data in the subset data.frame "SpainGer"
Goals.fit <- aov(GoalsGame ~ League, data = SpainGer)
summary(Goals.fit)
