)tol.logical, tol.num, tol.char, tol.factor, tol.date, tol.other |
A function or one of the shortcut character strings or a list thereof, denoting the tolerance function to use for a given data type. See "details", below. |
tol.num.val |
Numeric; maximum value of differences allowed in numerics (fed to the function given in |
int.as.num |
Logical; should integers be coerced to numeric before comparison? Default FALSE. |
factor.as.char |
Logical; should factors be coerced to character before comparison? Default FALSE. |
tol.date.val |
Numeric; maximum value of differences allowed in dates (fed to the function given in |
tol.vars |
Either |
max.print.vars |
Integer denoting maximum number of variables to report in the "variables not shared" and "variables not compared"
output. |
max.print.obs |
Integer denoting maximum number of not-shared observations to report. |
max.print.diffs.per.var, max.print.diffs |
Integers denoting the maximum number of differences to report for each variable or overall.
|
max.print.attrs |
Integers denoting the maximum number of non-identical attributes to report. |
... |
Other arguments (not in use at this time). |
max.print.diff |
Deprecated. |
The following character strings are accepted:
tol.logical = "none": compare logicals exactly as they are.
tol.num = "absolute": compare absolute differences in numerics.
tol.num = "percent", tol.num = "pct" compare percent differences in numerics.
tol.char = "none": compare character strings exactly as they are.
tol.char = "trim": left-justify and trim all trailing white space.
tol.char = "case": allow differences in upper/lower case.
tol.char = "both": combine "trim" and "case".
tol.factor = "none": match both character labels and numeric levels.
tol.factor = "levels": match only the numeric levels.
tol.factor = "labels": match only the labels.
tol.date = "absolute": compare absolute differences in dates.
tol.other = "none": expect objects of other classes to be exactly identical.
A list with names mapped to x can be used to specify tolerances by variable. One unnamed element is supported
as the default.
tol.vars: If not set to "none" (the default) or a named vector,
the tol.vars argument is a character vector denoting equivalence classes
for the characters in the variable names. A single character in this vector means to replace that character
with "". All other strings in this vector are split by character and replaced by the first character in the string.
E.g., a character vector c("._", "aA", " ") would denote that the dot and underscore are equivalent (to be translated to a dot),
that "a" and "A" are equivalent (to be translated to "a"), and that spaces should be removed.
The special character string "case" in this vector is the same as specifying paste0(letters, LETTERS).
A list containing the necessary parameters for the comparedf function.
