‘factor(x, exclude = null)’ applied to a factor without ‘na’s is a no-operation unless there are unused levels: In that case, a factor with the reduced level set is returned. ‘as.factor’ coerces its argument to.

Trying to login after 2-factor authentication results in "wrong verification code. Feb 25, 2013is the general rule to use factor when the variable being used to determine the shape/size/colour is discrete, and not continuous? Or is there another use of factor in this context?

Dec 6, 2018the complete conversion of every character variable to factor usually happens when reading in data, e.g., with stringsasfactors = true, but this is useful when say, you've read data in. See the warning section of ?factor: In particular, as.numeric applied to a factor is meaningless, and may happen by implicit coercion.

To transform a factor f to approximately its original numeric values,. Feb 22, 2018a load factor=1 hashmap with number of entries=capacity will statistically have significant amount of collisions (=when multiple keys are producing the same hash). Mar 29, 2021change your line where you are making the factor to make it an ordered factor, and specify the exact level names.

May 5, 2015filter factor levels in r using dplyr asked 10 years, 8 months ago modified 10 years, 8 months ago viewed 67k times When creating the factor from b you can specify the ordering of the levels using factor(b, levels = c(3,1,2,4,5)). Mar 4, 2010i have data frame with some numerical variables and some categorical factor variables.

The order of levels for those factors is not the way i want them to be.
