Hello again!
I'm using python, rpy2, and R for a project. It's actually pretty
interesting. Anyhow, I pass in an R file to the python program. However,
I am getting the following errors, which seem more like R errors(?):
Loading required package: gstat
Loading required package: automap
Error in coordinates(x.df) <- ~x + y :
could not find function "coordinates<-"
In addition: Warning messages:
1: In library(package, lib.loc = lib.loc, character.only = TRUE,
logical.return = TRUE, :
there is no package called gstat
2: In library(package, lib.loc = lib.loc, character.only = TRUE,
logical.return = TRUE, :
there is no package called automap
Traceback (most recent call last):
File "reg4.py", line 38, in <module>
spat1.spat1(file1=file1,file2=file2)
File "/usr/local/lib/python2.7/site-packages/rpy2/robjects/functions.py",
line 86, in __call__

**kwargs)

res = super(Function, self).__call__(*new_args, **new_kwargs)
rpy2.rinterface.RRuntimeError: Error in coordinates(x.df) <- ~x + y :
could not find function "coordinates<-"
I've checked and gstat and automap are both there. Here is the actual R
code:
spat1 <- function(file1,file2) {
require(gstat)
require(automap)
x.df <- read.table(file=file1,header=TRUE)
coordinates(x.df) <- ~x+y
zz <- scan(file=file2,what="character")
proj4string(x.df) <- zz
png(file="map1.png")
u <- autoKrige(x.df@data[,1]~1,x.df)
plot(u)
return(u)
}
I know that there are a few people who have used both rpy2, python and R,
so I thought I'd launch this out.
Thanks in advance for any help.
Sincerely,
Erin
