Hi all,
I am on CentOS 7.2 (Linux x86_64) with R from EPEL.
Maybe I get the documentation wrong but it seems, the variable
R_LIBS_SITE in Renviron is ignored while, for example, R_LIBS_USER is
not.
What R tells me:
R version 3.3.1 (2016-06-21) -- "Bug in Your Hair"
...
Platform: x86_64-redhat-l
Hello,
May I ask your help?
I would like to do System Identification using time series data which has
transport delay.
First of all, I would like to identify the following parameters (K, Tau, TD)
for SISO case in the following Laplace domain equation:
K, Tau, TD: ymodel = (K/(Tau*s +1
Hi everyone,
My name is Marcela, I am bachelor student of statistics.

I know that currently the Mixstock package is not available on CRAN, I have
downloaded the Mixstock v.0.9.5.1 from CRAN's archive, but this version is not
supported by R v.3.3.1, for this reason I have used an older version of R (v.
2.14). I have followed, without any problems, all the passages

Hello, there,
My patterns are defined by variables, for example:z="h"v="x"
I have a vector:
a=c("th","mx","t")
I would like to find elements in vector a that contain either "h", or "x"
grep("h|x", a) apparently works. However, when I tried: grep(z|v,a), it did not
work. Can anyone help how to han
Dear Marcela
Can you clarify what you mean by a double entry table?

Hello,
Is this what you mean?
dat <- data.frame(x = rnorm(100), A = factor(sample(3, 100, TRUE)), B
= factor(sample(3, 100, TRUE)))
xtabs(~ A + B, dat)
Hope this helps,

Hi
This is a continuous time system. Are you willing to discretize the model?

Another approach using in-place replacement and thinking with matrix
operations instead of vector operations:
DF <- matrix( c( 0, 0, 1, 0, 0
, NA, 0, 1, 1, 0
, 0, 1, 0, 0, NA )
, byrow=TRUE
, nrow=3 )
DF2 <- DF
DF2[ , -1 ] <- ifelse( !is.
The | symbol has a completely different meaning in R syntax than it has in
regular expression syntax. R hands of pattern strings to the regex library
without looking inside the strings any more than it has to. Likewise, the
regex library has no clue about R syntax. Your attempt failed to create
"The | symbol has a completely different meaning in R syntax than it
has in regular expression syntax."
Well, actually it doesn't -- loosely speaking, they both mean "or" (ok
-- interpreting concatenation as "or" is a bit of a stretch). Perhaps

It might help if you specify your hardware, OS (presumably Windows?)
and version, and your R version. Also possibly how large your vectors
are and what other processes you have running.
Other than that, I have no clue, of course.

Hi All,
I have been working on a Competing Risks analysis using the mstate package
and when I run my analysis I was surprised to see the cumulative incident
function ending substantially before my data set did.
You can reproduce the behavior (kind of) using the data that was provided
with mstate:
Hi,
one possible solution is to use ltext().
ltext(xcoord, ycoord, label="TEST", adj=c(0.5,0.5))
You have to know or to find out best fitting coordinates.
Via adj you can control, if the text should adjust left, center or right
to the coords, and above, center or bottom of them.
HTH,
Rainer Hu
