Your initial post mentions 70 columns in your data table, yet the example
shows 67 counting the initial "labels" term in the header. I would suggest
adding "row.names = NULL" to force row numbers and see how that behaves, e.g.
rawdata <- read.table("r_work/train_data.csv", header=T, sep=",",
na.strings=0, row.names = NULL)
Otherwise, you might want to consult the R Manual where it states:
header a logical value indicating whether the file contains the names of the
variables as its first line. If missing, the value is
determined from the
file format: header is set to TRUE if and only if the first row
contains one
fewer field than the number of columns.
So, you might also want to count up your column names in the header line.
