[R] sql query over local tables
Hi i have to table with IDs in each one. I want to make a join (as in sql) by the ID. Is any way to use the RODBC package (or other) in local tables (not a access, mysql, sql, etc. ) and made the join?

[R] Age-Length key with kimura algorith
Hi, Im looking for information to implement the kimura method (kimura Chikuni. 1987. Mixtures of empirical distributions: an interative application of the age length key) for calculation of fisheries age-length key. If someone have a manuals, methodology or examples about it I will be really gratefull if you could share it.

[R] It is possible to Expand RAM with HD space?
I'm using R in a winXp machine. I have problems with the size of my database (xyz), anyone know if is possible to use some kind of swap memory, in order to expand my real RAM and use HD space for the processes? I'm trying to make a variogram, and I don't want to sacrifice the precision of the data, e.g. using mean or median by defined pixels or something like that (now I have to do that, or use other software like SAS).

Re: [R] Reasons to Use R
I have a Dell with 2 Intel XEON 3.0 procesors and 2GB of ram The problem is the DB size. -Mensaje original- De: Gabor Grothendieck [mailto:[EMAIL PROTECTED] Enviado el: Lunes, 09 de Abril de 2007 11:28 Para: Jorge Cornejo-Donoso CC: r-help@stat.math.ethz.ch Asunto: Re: [R] Reasons to Use R Have you tried 64 bit machines with larger memory or do you mean that you can't use R on your current machines? Also have you tried S-Plus? Will that work for you? The transition from that to R would be less than from SAS to R.

We are still using SAS because R can't handle own db, and of couse we don't want to sacrify resolution, because the data collection is expensive (at least in fisheries and oceagraphy), so.. I think that R need to improve the use of big DBs. Now I only can use R for graph preparation and some data analisis, but we can't do the main work on R, abd that is really sad. __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] Plot symbols dimensions
I have the same question/problem. I have a UTM plot, so the axes are in meters, and I need to represent each point of 50*50 m.

[R] Glm and random effects
Hi, I'm traing to use the GLM to find tendences on my data. E.G. Data.frame: MyData Len ZoneYear 121 2002 21 1 2003 32 1 2004 32 2 2002 32 2 2003 31 2 2004 3 3 2002 4 3 2003 3 3 2004 32 4 2002 4 4 2003 5 4 2004 I want toi fing tendences on the len, if they change over the year (the anova say yes), but I wan't to include the zone as a Random effect So, I have something like this: SalGLM - glm(MyData$Len ~ factor(MyData$year)) summary.glm(SalGLM) But, I really don't know how to incorporate the zone as a random effect, anybody could help please?

Re: [R] substitute NA values
This could work, but not with big matrix!
year - c(1990,1995,2000,2005)
Prod - c(2478,3192,NA,1594)
matrix - data.frame(cbind(year,Prod))
for (i in 1:dim(matrix)[1])
{
if (is.na(matrix[i,2])) {matrix[i,2] - 0}
}

[R] RV: By sentence
Hi dear listers Do you know how to made a mean by one or more categorical variables? I can do that quite easy on SAS by in R I just can't do it E.g. Some fishes Sex Lenght male15 fema20 fema17 fema19 male 18 So the idea is mean(Lenght) by sex, in order to have sex: Male mean=XX Sex: Fema mean=YY In this case is quite easy to do it by a loop, but I have a huge DB so is not an option. Any suggestion?
