Hello,
Previously, I tried all the classification methods as mentioned on your Github and that worked. However, I am trying the supervised method using Random forest and I get the following error consistantly. Please help me out regarding this issue. It will be highly appreciated. Thank you.

Error:
classification<-fieldSegment(mosaic = Test, trainDataset = training_sam)
[1] "Starting supervised classification ..."
Error in predict.randomForest(modelFit, newdata) :
variables in the training data missing in newdata

Code:

soil<-fieldView(mosaic = Test, editor = TRUE)
soil<-st_as_sf(st_sample(soil, 200))
soil$class<-'soil'

plants<-fieldView(mosaic = Test, editor = TRUE)
plants<-st_as_sf(st_sample(plants, 200))
plants$class<-'plants'

training_sam<-rbind(soil,plants)

classification<-fieldSegment(mosaic = raster(Test), trainDataset = training_sam)

I tried to build shape file as you described in section. 3, however, menu button was not displayed in plot section on my Studio. How can I fix it?

Trying to run the demo in the description on the given dataset and on one of my orthos

• after placing the trial bounds and hitting the done button, the error happens
• I've tried manually loading mapedit and dplyr and this has not affected the error and it replicates every time

Steps: load packages, load ortho and .csv file, create fieldMap, fieldShape_render(), place trial bounds in visualization, click "Done", ERROR

Trying to install the FIELDimageR.EXTRA in Rstudio. I downloaded the ZIP and followed all steps and code. Then error with this after:

library(FIELDimageR.Extra)
Error in library(FIELDimageR.Extra) :
there is no package called ‘FIELDimageR.Extra’

Please advise, I can send the results of the ZIP package installation and such if the problem would be there. My prof walked out and tasked us with solving this as our assignment since no one in class could get it to work.
