R Users,
I just upgraded my version of R from R-2.15.0 to R-2.15.2 and installed the
latest versions of LyX and MikTex running Windows 7 Ultimate, 64-bit OS. Prior
to the upgrade, I was using Lyx with knitr to generate a document with no
problems. However, after the upgrade, and using the
Thanks, Yihui!
Luckily I kept R-2.15.0 and left it untouched (so I can continue to use that
for now). If it helps any, I was able to go back into Lyx and change the path
to point to R-2.15.0 and I also changed the windows path environment variable
to point to the old version. After doing
I haven't used it yet, so I can't comment about the stability or
appropriateness of it, but R.NET looks somewhat promising for this:

In the example below, I don't see any $$$ separators. Are you sure this is
supposed to be the separate or just a single dollar sign? If this is the case,
you don't specify what is to happen when multiple separators appear next to
each other. From your example, it appears that two separators
You could use something like this:
#Generate 26 simulated data points
y=rnorm(26)
x=1:26
your.labels=letters
#Plot data
plot(x, y, xlim=c(min(x), max(x)+.25), ylim=c(min(y), max(y)+.25))
#Label points
text(x+.15, y+.15, your.labels)
You could also use the textxy function in the calibrate
I'm guessing that you have more elements in your weights vector than you have
observations? It's hard to tell without seeing your data.
See below:
#Generate fake data
y=rnorm(10)
X1=rnorm(10)
X2=rnorm(10)
X3=rnorm(10)
#Create a 10 element vector of weights
wts=abs(rnorm(10))
#weighted lm
What about something like this:
#Create dummy data
mydf=data.frame(matrix(rnorm(1000), ncol=100))
#Obtain summary stats
my.vars=apply(mydf, MARGIN=2, FUN=var)
my.std=sqrt(my.vars)
#Plot summary stats
plot(my.vars, col=red)
points(my.std, col=blue)

The Anderson-Darling Test and the Shapiro-Wilk test have considerably more
power.
I'd refer you to a non-R related discussion board for statistics related
questions. Perhaps the following might be more useful:

don't you use this:
seq(from=0, to=100, by=.01)/100

however. Can you be a bit more specific on what each row/column is?
