Dear R-friends,
the dataset I am using (data.it) is organized as follows
partner stp btp reg
hk 0.64 1 s
ger 0.27 1 d
tur 0.27 1 s
rom 0.24 1 s-f
por 0.24 1 s
spa 0.23 1 s
gre 0.22 1 d-f
aus 0.17 1 d
uk 0.16 1 s
be 0.16 1 d
arg 0.15 1 s
usa 0.13 1 d-f
fra 0.13 1 s
neth 0.05 1 s-f
pol 0.05 1 d
bra 0.04 1 s
ko 0.006 1 s
un -0.009 2 d-f
svi -0.022 2 s-f
cin -0.040 2 d
ru -0.074 2 d-f
mex -0.077 2 s
... ... ... ...
and plotting it using dotplot, I specified the script as:
library(lattice)
attach(data.ita)
dotplot(reg~stp | partner, data=data.ita, groups=btp,
xlab=list("Data -
it",cex=1.5),col=c("black","red"),aspect=0.3,as.table=TRUE,xlim=c(-1,1))
detach(data.ita)
In the resulting plot the variable "reg" is ordered alphabetically.
Instead, I would like the variable to be plotted in the following order:
"s", "s-f", "d", "d-f".
How can I do it?
Many thanks
Luca

Hi, I'd like to store N vectors of different lengths, and to be able to access them with an index, and eventually free the memory for one of them without modifying the indexes to the others. In C this would be a vector of N pointers that point to memory cells independently allocated. For example int *pv[3]; pv[0] = (int *) malloc(13 * sizeof(int)); pv[1] = (int *) malloc(7 * sizeof(int)); pv[2] = (int *) malloc(110 * sizeof(int)); free(pv[1]) ... What is the best data type (or class) in R to do such a thing? Thank you!
