publication statistics from Web of Science
Dear list,
This is a bit of an off-topic question, but I'm hoping to get some
advice from more experienced people. I've used the website "Web of
Science" to manually collect publication counts responding to several
keywords as a function of date, since the 1960s.

lmer random effect model matrix question
I have one fixed effect, sor, with two levels. I have eight lots and
three wafers from each lot. I have included the data below.
I would like to fit a mixed model that estimates a covariance parameter
for wafer, which is nested in lot, and two covariance parameters for
lot, one for each level of sor. The following command fits the model
that I want, except for it estimates the correlation

Generating a "conditional time" variable
Hi everyone,
Please forgive me if my question is simple and my code terrible, I'm new to
R. I am not looking for a ready-made answer, but I would really appreciate
it if someone could share conceptual hints for programming, or point me
toward an R function/package that could speed up my processing time.
Thanks a lot for your help!

Placing axes label strings closer to the graph?
Folks,
I have placed an example of a self-contained R program later in this
mail. It generates a file inflation.pdf. When I stare at the picture,
I see the "X label string" and "Y label string" sitting lonely and far
away from the axes. How can these distances be adjusted? I read ?par
and didn't find this directly.
I want to hang on to 2.8 x 2.8 inches as the overall size

problem with data
Hello all!
I have a problem with my data in R. When I want to plot the following data,
I have a problem with y scale. The maximum value is cc. 10 degrees and in R
is about 100.
I use this code:
fasy<-read.table("gridd1.txt",sep="\t",dec=",",header=T,row.names=1)
# here are the years:
x <- as.numeric(rownames(fasy))
# extract a series that you want to plot:

Calculating the Sharpe ratio
Hi useRs,
I am trying to calculate the Sharpe ratio with "sharpe" of the library
"tseries".
The documentation requires the univariate time series to be a
portfolio's cumulated returns. In this case, the example given
data(EuStockMarkets)
dax <- log(EuStockMarkets[,"FTSE"])
is however not the cumulated returns but rather the daily returns of the
