search for: coord2

...ce of code that generates simulated variables. after variable generation I use them in several analyzes. However, when I use a for to repeat the procedure 1000 times I get an erro message in one of the "for" steps, precisely at this time: gls.temp<- gls(y2 ~ x2,correlation=corExp(form=~coord2[,1]+coord2[,2])) # coord 2 are spatial coordinates and the error message is: Error in gls(y2 ~ x2, correlation = corExp(form = ~coord2[, 1] + coord2[, : false convergence (8) I don´t know what causes this error. My problem is that this error stops all the calculations during the for looping and a...

...am conducting. The package works fine when I call the functions from the command line as the examples instruct. However, I am attempting to step through some of the functions so that I can obtain a better idea of what is going on. I have come to the following command: calc.dist(coord1.day.index,coord2.day.index,id.day.index) I know what this is supposed to do, it is calculating the geographic distance between a series of latitude and longitude points. However, I am informed by R that no such function exists. I searched through the whole package for a function declaration, rooted through the R...
