Dear fellow R users, I am trying to run the random forest and Yaimpute packages in R to impute a grid to project in a gis. However, after running the imputation I keep getting an error in the rownames. This sounds simple enough, but I cannot figure out what these rownames are reffering to. Any ideas? I am fairly new to R so im sure it is an easy fix. Any help would be awesome.
Thanks, Chris > 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= 2000) > outfile <- list(Type = "D:/R_Desktop_Data/RF_RespSurf/RespSurf_Reg.asc") > xfile <-list(sinaspect ="C:/Users/jacksonjordancm/Desktop/R_Desktop_Data/RF_NNimp/ModelI/ASCII_Files2/sinaspect.asc", habitat ="C:/Users/jacksonjordancm/Desktop/R_Desktop_Data/RF_NNimp/ModelI/ASCII_Files2/habitat.asc", elevation ="C:/Users/jacksonjordancm/Desktop/R_Desktop_Data/RF_NNimp/ModelI/ASCII_Files2/elevation.asc", disttowat ="C:/Users/jacksonjordancm/Desktop/R_Desktop_Data/RF_NNimp/ModelI/ASCII_Files2/disttowat.asc", disttoroad ="C:/Users/jacksonjordancm/Desktop/R_Desktop_Data/RF_NNimp/ModelI/ASCII_Files2/disttoroad.asc", slope ="C:/Users/jacksonjordancm/Desktop/R_Desktop_Data/RF_NNimp/ModelI/ASCII_Files2/slope.asc", cosaspect ="C:/Users/jacksonjordancm/Desktop/R_Desktop_Data/RF_NNimp/ModelI/ASCII_Files2/cosaspect.asc") > AsciiGridImpute(type.rf, xfile, outfile) Rows per dot: 19 Rows to do: 1900 ToDo: ....................................................................................................
