[R] random between two values
Hi, I would obtain a random value between two (for example between 40.15 and 56.58 I would have only one value). I'm looking for a package/a function which could do this. Could anybody help me please?

[R] to raise in a loop more than 1
I would raise x,y and z in a loop but I won't raise of 1. I tried this but it
doesn't work
mydata=matrix(nrow=1500,ncol=3)
i=1
for(x in 0:10){
for(y in 0:20){
for(z in 0:10){
mydata[i,]=c(x,y,z)
i=i+1
z=z+2}
y=y+4}
x=x+2}
And I would have something like that
x y z
0 0 0
0 0 2
0 0 4
0 0 6
0 0 8
0 0 10
0 4 0
0 4 2
...
Could anybody help me?
I don't work on a special package to do it...
Thanks
Cordialement

[R] Variogram fitted by Cauchy
Hi I'm using R(2.9.0) and gstat package under Windows to plot sample variograms. When I want to fit them, I don't have the possibility to choose Cauchy functions. Under Mathematica for example, we have it and it seems to be the best one to fit the variograms I have I tested the others functions, they can fit but I would,if possible, use the Cauchy one. If anybody knows something about it, I would know, even with another package To show what I want to do, here is my code mydata=read.table(97MHz_15cm_V3.txt) colnames(mydata)=c(x,y,z,E,taille) g=gstat(id=zinc,formula=mydata[,4]~1,locations=~x+y+z,data=mydata) g.var=variogram(g,cutoff=2500,width=100) modele=vgm(model=Exp,range=2000) vario=fit.variogram(g.var,modele) Thanks!

[R] plot two variograms on a same graph
Hi, I would know how to plot two variograms on a same graph. I can plot one by one but I would draw both on the same one. Is it possible? Do i need any special package? Thanks!
