mark 0.2.0

Changes

package_available() now visibly returns TRUE/FALSE
remove_na() now has methods for lists and factors
environments() now has it's own print.mark_environments() method rather than calling cat() within the function itself
array_extract()'s first argument is changed from arr to .arr
diff_time() now defaults to using UTC (Related to #32)
print.note() method has been updated (Related to: #33):
- to print x normally, without the note class when just the note has to be seen
- an internal function now handles the note formatted for class noted
changes to fact()
- fact() now returns a vector with a fact element
- fact.character() correctly labels NAs #24
- fact.factor() not longer simply returns x but rather updates the levels and integer values to confirm with other fact() methods. fact.factor() will retain all levels of the original value, reorder the levels, and append NA if necessary
- fact.fact() added to return a correctly formatted fact()
- fact.logical() now orders levels as TRUE then FALSE, and NA if present
- fact.Date() and fact.POSIXt() added, which simply call fact.numeric()
- print.fact() method added to print a fact vector as a factor
- as_ordered.factor() and as_ordered.ordered() now call fact() to check levels

functions that check if an argument is a vector no long use is.vector() directly; arguments passed with attributes that when removed fulfill is.vector() are accepted
todos() and fixmes() now correctly show tags for .Rmd files
correction to error message in limit()
adds missing sort argument to props()
pseudo_id.factor() no longer returns NA_integer when a value is NA or a level is NA and correctly resets the order of the levels from the factor to their order of appearance
flip.data.frame() no longer coerces single column data.frames #36

fact.pseudo_id() and pseudo_id.pseudo_id() methods added
adds as_ordered() to quickly create ordered factors using fact()
adds char2fact() to convert character vectors (or columns in a data.frame) to factors based on the number unique values
adds tableNA() to make a table from NA values
round_by() gains an additional argument include0 which if FALSE will replace 0 values with by
assign_labels.data.frame() gains an additional argument .missing to set how to control for missing labels: you can now use a warning for a missing label (instead of an error) or silently ignore any missing labels
sort_names() gains a new argument numeric to try to sort names of x by their numeric value #26
adds struct(), a simplified version of struct()
adds more fact() methods
- fact.integer() #30
- fact.haven_labelled() #31
todos() and fixmes() gain an additional argument path to specify a directory or file to search within #25
print.pseudo_id() added for a cleaner print
between_more() accepts vectors for left and right params
