Regular expression help
Hi Duncan, why not split on / and take the correct elements? It is not as elegant as regex but could do the trick.

"(^| +)([^/ ]*/?){0,2}", with the first "*" replaced by "+" would be a bit better.

user coordinates and rug plots in lattice graphics
Dear R list members, I'd like to produce rug plots at the bottom of panels in a trellis display (using the lattice package), but par("usr") doesn't return user coordinates for panels, and consequently rug fails, as the following example (suggested to me by Georges Monette) illustrates: > x <- rnorm(50) > y <- rnorm(50) > f <-

Beginner's Question on Linear Regression Models
Hi Folks, Could anyone point me to a good reference on linear regression models? Specifically, I am trying to gain an intuitive feel for how the standard error values are calculated for the parameter estimates. My understanding is that these are computed using the variance-covariance matrix computed from the input data matrix. Although I think I understand the math, I still don't have a

Connectiion to UPS via SNMP
Hi NUT-Users, we work with a GE LP 33 UPS and an Advanced SNMP WEB Interface Card. This card supports the RFC1628 Definition. So I think this combination work together with NUT and the snmp-driver, correct? I installed the networkupstools on my Debian Sarge with apt-get (nut & nut-snmp). After configuration I start the upsd and upsmon. I get following output in /var/log/syslog: ... Aug 3

Vignette problem and CRAN policies
Hello, All: The vignette with the sos package used "upquote.sty", required for R Journal when it was published in 2009. Current CRAN policy disallows "upquote.sty", and I've so far not found a way to pass "R CMD check" with sos without upquote.sty. I changed sos.Rnw per an email exchange with Prof. Ripley without solving the problem; see below. The

Hi, I have the panel data of income statement of several banks. The date 9803 means 1998-Q1, 9806 means 1998-Q2, etc. I transform the date code to 1 (for 1998Q1), 2 (for 1998Q2), ...., 16 (for 2011Q4) where 1, 2, .... are placed in Col1. Now the income statement of a specific quarter is actually the accumulation from the beginning of the year. For example, the cost data of 1999Q3 is the

With just a single citEntry(), citation produces the expected output, with BibTeX entry: >

Slow printing in batch?
For doumentation purposes I run a batch R program that does reshaping etc. of data and finally prints things.

Any clues why R uses 4 min to print a 1129\times 6 dataframe in batch mode? The scrit I use to run R is: c:\stat\r\%R_VERS%\bin\Rterm --no-restore
