Question

I know that to get a row from a data frame in R, we can do this:

data[row,] 

where row is an integer. But that spits out an ugly looking data structure where every column is labeled with the names of the column names. How can I just get it a row as a list of value?

Answer 1

Data.frames created by importing data from a external source will have their data transformed to factors by default. If you do not want this set stringsAsFactors=FALSE

In this case to extract a row or a column as a vector you need to do something like this:

as.numeric(as.vector(DF[1,]))

or like this

as.character(as.vector(DF[1,]))
