Introduction to Factors in R. Factors play a crucial role in data

WebR Documentation Factors Description The function factor is used to encode a vector as a factor (the terms ‘category’ and ‘enumerated type’ are also used for factors). If argument ordered is TRUE, the factor levels are assumed to be ordered. For compatibility with S there is also a function ordered . WebIn this case, the median of a numeric vector is normally defined as the mean of the two middle values. However, for ordered factors the mean is not defined. The argument ordered_low cures this problem. If ordered_low = FALSE (the default), then the larger of the two middle values is returned (this value is called ‘hi-median’ in mad).
