Rd problems
Hola!
I have the following in a .Rd file:
\eqn{\mbox{coef} = c(\mbox{coef}[1],\ldots, \mbox{coef}[n]) }
{coef = c(coef[1], coef[2], \dots, coef[n])}
However, both arguments come out in the latex file!
Whats happening?

Apparent bug in summary.data.frame() with columns of Date class and NA's present
Hi all,
Based upon an exchange with G?ran Brostr?m on R-Help today:
https://stat.ethz.ch/pipermail/r-help/2016-February/435992.html
there appears to be a bug in summary.data.frame() in the case where a data frame contains Date class columns that contain NA's and other columns, if present, do not.
Example, modified from R-Help:
x <- c(18000000, 18810924, 19091227, 19027233, 19310526,

table( , exclude=NULL) for factor objects
The NEWS file for R-1.7.0 says:
table() now allows exclude= with factor arguments (requested by
Michael Friendly).
But in a recent R-1.7.1beta:
> test <- c(1,2,3,4,5,1,2,3,4,5,NA,NA,1,2,3,4,5)
> table(test)
test
1 2 3 4 5
3 3 3 3 3
> table(test, exclude=NULL)
test
1 2 3 4 5 <NA>
3 3 3 3 3 2
> table( as.factor(test), exclude=NULL)

segfault in approx() (PR#6809)
This is R1.9.0, windows XP
I run across the following:
It is admittedly silly, but it shouldn't segfault:
test <- list(y=1:100, x=rep(NaN, 100))
approx(test, xout=rep(NaN, 10))
Bombs!

Minor nuisance with rw1071
Hola!
Starting with rw1071, just after starting Rgui the scope is not with
Rconsole, but some other place. This means I have to do a mouse click
in the Rconsole before starting to write the first command. Since I
always forget this, I end up writing the first command twice.
This is of course only a minor nuisance, but why is focus no longer
set to Rconsole window when start-up?

mgcv, gam
Hola!
I have some problems with gam in mgcv. Firts a detail: it would
be nice igf gam would accept an na.action argument, but that not the
main point.
I want to have a smooth term for time over a year, the same pattern
repeating in succesive years. It would be natural then to impose
the condition s(0)=s(12). Is this possible within mgcv?
I tried to obtain this with trigonometric terms, aca:

Rd problems --- followup
I should'nt have sent the last mail so fast.
Same problem with
\eqn{u_j = a_j + b x + c x^2, \quad j=1, \ldots, r-1}
{u[j] = a[j] + b*x + c*x^2 j = 1,\dots,r-1}
I thought the problem in the first case could have to do with
the use use of \mbox{} (with the braces) within the arguments
of \eqn, but here there are none braces in the arguments of \eqn{}{}.

Problem with breakpoints (strucchange)
Hola!
I am using package strucchange, and encounters the following:
> bp <- breakpoints(diesel90 ~ regress -1, h=NULL)
Error in La.chol2inv(x, size) : element (14, 14) is zero, so the
inverse cannot be computed
The obvious problems have been checked, that is, the model matrix is
of full rank. What can be causing this?
I can send some data if that can be of help.

Reading an upper triangular matrix
Hola!
I have data in the form of a symmetric distance matrix, in the file I
have recorded only the upper triangular part, with diagonal. The
matrix is 21x21, and the file have row and col names, and some other
information. I am trying to read with the following code (I tried
many variations on it, but all give the same error). The items in the
data file is delimited by white space.

R 1.9.0 alpha
I saw a reort on R-help (without answer) about not being able to load
old workspaces
(.RData files) in 1.9.0alpha. I have seen the same problem with some
of my workspace, although most of them loads without problems.
(rw1090alpha as of 17.03, windows XP).
Why will some workspaces not load?

arima
Hola!
I got problems using an objects returned from arima
(in KalmanSmooth(my.ts, ModArima$model), because
my.ts showed up to have storage mode "integer" (is.integer(my.ts was
TRUE).
Should storage.mode() of a ts be allowed to be integer,
should ts() someplace say storage.mode(ts.out) <- "double", or
maybe inside arima()
storage.mode(x) <- "double"

options(width= ) in rw1081
Hola!
I just downloaded and installed the factory-fresh
rw1081. Windows XP.
In my Rprofile file in the \etc subdirectory I put
(among others)
options(continue=" ")
options(width=65)
options(scipen=5)
options(show.signif.stars=FALSE)
R is honoring all of this on startup, exept
the width=65 option, which does'nt have any effect. I tried
other values for width also (70, 90) ,

bug(?) in chisq.test
This is a message for whoever maintains "chisq.test": For an
outcome more extreme than 2000 simulations, a Monte Carlo p-value of "<
2.2e-16" was printed. Ripley said the proper p-value for such cases
should be 1/(B+1) = 1/2001. This can be easily fixed by adding
"if(PVAL==0)PVAL <- 1/(B+1)" right after the following line in the code

USA map
R users,
In S, there was a function called usa() that
would draw the map of the United States, plus
it had other options for graphics. I have looked
but I can't find the equivalent in R. Is there one?
Thanks,

rsync
Hola!
I am now downloading r-devel to compile it on windows XP. The CRAN
source code page says "you will prefere to use rsync". I am googling
around, and cannot find anything about rsync on windows.
Anybody has any experience with rsync on windows?
