Hi, R listers,
I��m trying to compare a value of a row in a column to values of previous rows
in another column in a loop. ��i�� is just from first row to the last row. j is

to and j will be rows before row[i]. I want
If you execute the command
options(useFancyQuotes=FALSE)
before calling comp(s1) that error should go away.
dQuote() was being used inappropriately - its value depends on the
option "useFancyQuotes" so should really only be used for messages or
text that machines don't have to parse.

The distribution of the statistic $ndf * r^2 / (1-r^2)$ with the true
value $\rho = zero$ follows an $F(1,ndf)$ distribution.
So the t-test is the correct test for $\rho=0$.
Fisher's z is an asymptotically normal transformation for any value of
$\rho$.
Thus Fisher's z is better for testing $
Dear Phil,
Yes, that's a bit clearer. One can invent data configurations where certain
studentized residuals are undefined. For example, try the following:
y <- c(0, 0, 0, 0, 0, 1)
x <- 1:6
xx <- (1:6 - 3.5)^2
rstudent(lm(y ~ x))
rstudent(lm(y ~ xx))
plot(x, y)
plot(xx, y)
The plots should clar

You may be interested in looking at Reference Classes/objects (see
?setRefClass). This is a form of OO programming that is more similar
to C++ and Java. You could create a counter object that you could
then increment with syntax like:
x$inc()
x$inc(5)
The first would increment by the default (1
Dear Phil,
After reading your posting several times, I still don't understand what you
did. As usual, having a reproducible example illustrating the error would be a
great help. I do have a guess about the source of the error: glm() failed in
some way for the problematic case.
Best,
John

Minor correction, given your code, values less than 3 will be coded as "S"
since they are less than 15.23. In the code I suggested, values less than 3
will be coded as missing (NA).

I think it is doing exactly what you have told it to do, but that is probably
not what you want it to do.
First, you do not need a loop since the ifelse() function is vectorized. Read
the manual page and the examples carefully. Also you are coding ifelse() as if
it were the same as if() {} else
As the Posting Guide indicates, this is a text-only mailing list, and small,

Hi,
I'm having trouble with assigning a letter to a column based on the value
of another column.
Since I have separate data files I've saved then into one folder and I'm
reading them in separately into the function.
The code is below.
#F= fast; S= slow; I1= Intermediate score 1; I2=Intermediate

Hello,
I would like to draw a circle on top of a pie chart (The plot does not
need to fullfill scientific standards). The circle represents the
relation of a reference-value in comparison to the summed values of the
pie-pieces. To be able to do this I partly followed:

Hi guys,
I came across a strange phenomena and can't figure out why it happens by
myself so here we go.
I got a dataframe which consists of double numbers which I want to
check, row-wise if there are outliers in the rows.
So I iterate over the rows and create a glm using the numbers of that
This is pretty much standard. I'm quite sure that other stats packages do
likewise and I wouldn't know who "everyone" is. It is not unheard of that
textbook authors give suboptimal formulas in order not to confuse students,
though.
The basic point is that the t transformation gives the exact di

While I use this in C, I second Rolf on the general issue.
