Use as.numeric () to convert a factor to a numeric vector. Note that this will return the numeric codes that correspond to the factor levels. 2019-12-12 Factors in R come in two varieties: orderedand unordered, e.g., {small, medium, large} and {pen, brush, pencil}. For most analyses, it will not matter whether a factor is ordered or unordered. If the factor is ordered, then the specific order of the levels matters (small < medium < large). 2019-07-18 Before we can start, we need to create an example factor vector in R: set.seed(13579) # Set seed x <- as.factor( sample ( c (3, 5, 6, 9), 100, replace = TRUE)) # Example factor vector.

Factor. Factor variables are a special case of character variables in the sense that it also contains text. However, factor variables are used when there are a limited number of unique character strings. It often represents a categorical variable.

as.factor: Convert H2O Data to Factors Description. Convert a column into a factor column. Usage as.factor(x) Arguments The function factor is used to encode a vector as a factor (the terms ‘category’ and ‘enumerated type’ are also used for factors).

For this exampe, we're assuming that you're trying to plot some factor variable on \( x \) axis and \( y \) axis holds some numeric values. set.seed(357) x <- data.
