diff of two timestamps
Hi all,
I have the following problem: I have a csv-file consisting of timestamp
values (no dates), e.g.:
Timestamp1;Timestamp2;

I need a vector with the difference of the two timestamps, so I read the
data with the read.csv-function:
myObj <- read.csv("file.csv",header=TRUE,sep=";").

Multiple databases + switching databases
Hello,
I have an application that access two different DBMS - Firebird
and Postgres. So far, that''s ok. The problem is, depending on the
customer logged, a different database (Firebird) must be selected.
To make the things clearer:
Postgres: 1 database shared by all customers with these tables:
- user
- vehicle
- driver
Firebird: several databases with different names and identical

SAS-like method of recoding variables?
Dear R-helpers,
I am helping a SAS user run some analyses in R that she cannot do in
SAS and she is complaining about R's peculiar (to her!) way of
recoding variables. In particular, she is wondering if there is an R
package that allows this kind of SAS recoding:
IF TYPE='TRUCK' and count=12 THEN VEHICLES=TRUCK+((CAR+BIKE)/2.2);
Thanks for any help or suggestions you might be able

PROC MIXED RANDOM equivalence in R nlme
I am trying to reproduce some old SAS PROC MIXED code using R and nlme.
The data consists of emission readings from vehicles and fuel
properties. All variables are real numbers except "study" and "vehicle",
which are character. Unfortunately, since the data are confidential, I'm
unable to provide an example.
The original SAS v6.12 code is provided below:

Problems under Redhat EL3 and ext3
I am running into performance issues with ext3. Historically we had our
image files (pictures of cars, currently 5.3 million) sub divided into a
directory structure [0-9]/[0-9]/[0-9]/[0-9], where we would take the
first 4 letters/numbers of the file name and use that to put it into
this structure. Letters [a-cA-C] would become a 0, [d-fD-F] a 1, etc. As
the file names used to be based on VIN

PROC MIXED RANDOM equivalence in R nlme
Dear Dennis,
Your question assumes that people know both SAS PROC MIXED and R nlme. Only
a limited number of people do. Add the mathematical formulation of the
model. That will increase the number of people that can help you. Adding
the number of levels in each categorical variable and the number of
observation per group is useful too.

Replacing a character string when finding substring match
Dear R-experts,
I need to replace the values of a vector(tx) with a
word ('Vehicle') when the value of the vector contains
the word 'vehicle'. Sometimes, the value could be 'MCT
vehicle', or 'control-vehicle', etc.
I tried gsub like this
treatment<-gsub('vehicle','Vehicle', tx,

But then I end up with values like 'MCT

I assume you want the 'v' variable in panel.abline() to be interpreted
in the context of your x-axis, which here represents a factor
variable. Unless two factor variables have the same
