Hi colleagues, I am newbie with R and I am trying to train a very simple neural network, but the example is sending this error:
Error in `[.data.frame`(newdata, , object$model.list$variables) : undefined columns selected Could any one please help me with that? Here is my example code... library(neuralnet) setwd(dir = "C:/Users/yordan/Desktop/tested_data_results/alto_desbalance/ecoli-0-1-3-7_vs_2-6") headers = c("col1", "col2", "col3", "col4", "col5", "col6", "col7", "type") testData0
Hi Yordan,
Welcome to R!
I´m not so sure about your code, if you could provide the script you have used, or explain what you are actually trying to run, that would be helpful.
My questions would be: is that error happening when you run the neuralnet function?
Did you try running the whole script at once?
Your error is simple as it means that you did not define any columns to be used, i just can't know what you were trying to do, and what columns you would need to select.
I'm sorry if this doesn't help much,I'll be happy to help you further if possible!
Lucas
