Things seem to be fine until line 28, when I attempt to actually call the randomForest method. I'm new to R and am still getting used to the language.
The code is listed below:
{
install.packages("randomForest")
install.packages("biom")
install.packages("rjson")
library(randomForest)
library(MASS)
library(biom)
library(rjson)
getwd()
file.exists("Subramanian_et_al_otu_table.biom")
Subramanian_et_al_otu_table
Hi Isaac,
I think you need to specify the response column directly and not include it in the data call:
randomForest(table[, 1] ~ ., data=table[, -1], ...)
Here we are specifying that the response variable is in the first column (could also use table$rand) and the data we provide does not include this column.
Note [, -1] means all rows and NOT column one.
I hope this helps.
Hi
you have to use one of these cases:
1) after import data, use "attach(Data)
2) define rand, for example: rand
