Chris,
It's hard to troubleshoot without reproducible code. I suggest you post a
simple example of code that we can run. For example, use
dput(training[1:20, ])
to spit out the first 20 lines of the training data. Then simplify the
rest of the code as much as possible.
library(yaImpute)
training <- <<< insert output from dput(training[1:20, ]) here >>>
y <- subset(training, select = c(ResponseSu))
x <- subset(training, select = c(sinaspect, habitat, slope, elevation,
cosaspect, disttoroad, disttowat))
type.rf <- yai(x=x, y=y, method="randomForest", rfMode="regression", ntree=
20)
outfile <- list(Type = "RespSurf_Reg.asc")
xfile <-list(sinaspect ="sinaspect.asc", habitat ="habitat.asc", elevation
="elevation.asc",
disttowat ="disttowat.asc", disttoroad ="disttoroad.asc", slope
="slope.asc", cosaspect ="cosaspect.asc")
AsciiGridImpute(type.rf, xfile, outfile)
