There may be further changes when we cope better with multiple missing values. For now I am leaving the layout as it is currently:
The current keyboard is like this:
a) The add_na key command has now changed. Use the new one, which is in forcats and is fct_na_value_to_level
b) Changefct_lump function into fct_lump_min Still call the keylump.
factor: Make a factor from a numeric or character variable
anon: Anonymise factor levels, replacing them by a number. Optionally add a prefix, for example fct_anon(name, "n")
labelled: Create a labelled variable
collapse: Combine factor levels. For example fct_collapse(variety, trad="TRAD",improved=c("NEW","OLD"))
cross: Make interaction variable. For example fct_cross(variety,fertgrp, keep_empty=TRUE)
drop: Drop unused levels
expand: Add additional levels. For example fct_expand(Village, "New", "Newer")
add_na: Make missing values into an additional factor level. For example fct_na_value_to_level(fertgrp)
inorder: Order the factor levels by their appearance in the data
infreq: Order the factor levels by their frequency (
inseq: Order a factor with numeric levels
lump: Change all levels appearing less than min times into Other. For example fct_lump_min(Variety,10)
match: Make a logical variable with TRUE when levels are in the factor. For example fct_match(variety,c("NEW","OLD"))
other: Replace levels with Other. For example fct_other(variety, keep="NEW")
recode: Change factor levels. For example fct_recode(variety,improved="NEW",improved="OLD")
relevel: Reorder factor levels. For example fct_relevel(fertgrp,"0cwt",".5-2cwt")
reorder: Reorder levels using (default ofmedian of another variable. For example fct_reorder(variety,yield)
reverse: Reverse the order of the factor levels
shift: Shift the order of the factor levels
shuffle: Shuffle the order of the factor levels
