in the R data and so became a properly coded dummy variable.
Sorry for the obvious question and answer.
Perhaps this shoul work too:
sapply(strsplit(gsub(^\\W|\\W$, , testvec), ,),
function(x)sum(as.numeric(x))/2)

Hello - Thank you so much for the help. It works perfectly. I guess that as
many have pointed out, ggplot is a great package but there is a lack of
documentation and examples.

Jannis now it is working!!. I just have one mor request, please!
How I'm suppose to make a boxplot with anfang, when working with times, it

Because of the combinatorial nature of ggplot2, it is simply not
possible to provide an example that illustrates every single
combination of options. There are already over 600 example graphics
in the package - if you can't find one that exactly meets your need,
you need to buy the book and learn

Very, nice. Also tried on some other valid (200,2) and
invalid )2..2)
Could somebody recommend some textbook how to compute contrast when
there are interactions terms? Applied Linear Regression Models
(book) mentioned contrast, but I cannot extend it to the case where
there are interaction terms.

Hi,
I am using R 2.9.0. It seems the documentation for the calculation of
Canberra distance using stats::dist is ambiguous. Does anyone have the
original definition given in the Lance Williams paper from Aust. Comput.
J. 1, 15-20, 1967?
When there are zeros at certain position in both vectors,

Where does the table come from?
write.csv(t, file = t.csv)
looks like it would work

It was in some documentation along with using data.frame and other entries that
didn't work. Can't explain why I didn't try it as is.

Hello,
I have a problem with categorical variables and dummy encoding. I've a
factor and
for each pair (i,j) with i != j, I'd like to fit
res ~ a*x[i] - b*x[j]. A brief example with 3 variables:
a - b = 2
b - c = -1
c - a = 0
Thus I fitted the following model:
fit - lm(result ~ X + Y)
If I have data that I feed into shapio.test and jarque.bera.test yet they seem
to disagree. What do I use for a decision?
For my data set I have p.value of 0.05496421 returned from the shapiro.test and
0.882027 returned from the jarque.bera.test. I have included the data set below.
Thank you.
