Microsoft Scripting on WINE
I have a specialist piece of scientific software that I am trying to get to run in WINE (0.9.59 running in Ubuntu 8.04). I have installed the software, but when I run it I get a message saying "Microsoft Scripting needs to be installed. Please install the latest version of Internet Explorer."
Any ideas what to do?

testing slopes
Hello
Instead of testing against 0 i would like to test regression slopes against -1. Any idea if there's an R script (package?) available.
Thanks for any hint.

R package for visualizing/analyzing accelerometry data?
Hello All -
Any recommendations or suggestions for neat ways to visualize data
taken from a 3-axis accelerometer? My study species is aquatic, so I
would be interested in movement in the 3 dimensions in addition to
being able to incorporate the time series as well. Is there a package
in R that might be useful for this?
Thank you in advance,
Jen

Superponer mapas en ggplot
Buenos días. Tengo dos mapas que hago con ggplot (abajo) y necesito
superponer el 2º al 1º. En el 1º se representa la variable PA, binomial (0,
1), en gris, y en el 2º la variable ExtTG7085, que es numérica y va de 0 a
200. La 2ª es un gradiente en rojo. Lo ideal sería que donde coinciden el
rojo de la 2ª se viera más oscuro, pero supongo que eso no es fácil. Podría
también ser en otro color, pero

Linking 2 columns in 2 databases and applying a function
...for solutions on the net, with no luck
(I'm relatively new to R and the help pages are still a bit opaque to me).
It seems like the functions "apply" or "lapply" are key, but I can't make
sense of their syntax.
Any advice/help?!?
Many thanks,
Ryan

Use of geometric mean for geochemical concentrations
A statistical question, not specific to R.
I'm asking for a pointer for a source of definitive descriptions of what
types of data are best summarized by the arithmetic, geometric, and harmonic
means.
As an aquatic ecologist I see regulators apply the geometric mean to
geochemical concentrations rather than using the arithmetic mean. I want to
know whether the geometric mean of a set of chemical concentrations (e.g.,
in mg/L) is an appropriate representation of the expected value. If not, I
want to explain...

Dear all, I am a new user of R. I would like to know how to get fund's returns in percentage (%). For example, I use: R <- ts(read.xls("FundData"), frequency = 12, start = c(1996, 1)) Whith this program, the returns are like 0.0152699. But, I would like to have 1.52%. Please advise me about the function. Thanks! Fabrice

puntos para que se vean. Puedo hacer los puntos más pequeños, pero
entonces quedan separados y yo quiero que rellenen el mapa.
Gracias, como siempre,
