Hola:
Como dice Carlos, algo así, por ejemplo:
transforma <- function(df) sapply(df, function(x)
ifelse(x%in%c("x1","x2","x3"),
"prueba1",ifelse(x%in%c("x4","x5","x6"),"prueba2",x)))
> transforma(df1)
col1
[1,] "prueba1"
[2,] "prueba1"
[3,] "x11"
[4,]

Pregunta sobre rLandsat
Hola Ángel:
Yo creo que tendrías que establecer el sistema de coordenadas de
referencia de tu objeto raster antes de salvarlo como GTiff. Algo así:
crs(r1) <-"+proj=utm +zone=14 +datum=WGS84"
Saludos,
Marcelino.

repeatability/intraclass with nested levels
I have a spectrophotometric dataset with repeated measures of a value
at 200 wavelengths for each of 150 individuals.
I would like to use the repeated samples to at each wavelength to look
at measurement/observer error, compared to difference between
individuals error
I have looked at doing this with icc{irr} or using an anova approach,
but I am unclear how to acheive this given that there

cluster analysis: mean values for each variable and cluster
Hi all!
I'm new to R and don't know many about it. Because it is free, I managed to

Here is my problem: I did a cluster analysis on 30 observations and 16

partial mantel tests in ecodist with intential NA values.
I would like to perform partial mantel tests on only within group values, with "between group" values assigned to NA.
This is possible in package ncf partial.mantel.test, however this sues a different permutation to that used in ecodist.ecodist will not accept data with NA values, returning a "matrix is not square error.
is it possible to perform this test in ecodist?
many thanks
