The function set_limits() adjusts the limits according to the number
of relevant decimal places and according to the transformation requirement.

sl,
sl_sf,
sf_option = "tight",
xform = c("no", "no"),
shift = c(0, 0),
ivl_side = "lower"
)A list with the following elements is returned:
A character string that specifies the option concerning the significant figures.
A vector of two character strings that specifies the transformation of the response and the time variable.
A vector of two values to be added to the values of the
transformed \(x\) and/or \(y\) variables (specified via the
xform parameter).
A numeric value or a numeric vector of the release limit(s)
on the original scale. If NA was passed in, NA is returned.
A numeric value or a numeric vector that specifies the
significant figures of the release limit(s). If NA was passed in,
NA is returned.
A numeric value or a numeric vector of the adjusted (as specified
by the sf_option parameter) release limit(s). If NA was
passed in, NA is returned.
A numeric value or a numeric vector of the adjusted and
transformed, if applicable (as specified by the the sf_option
parameter and the second element of the xform parameter,
respectively), release limit(s), otherwise the same as rl.
A numeric value or a numeric vector of length 2 of the
specification limit(s) on the original scale.
A numeric value or a numeric vector of length 2
that specifies the significant figures of the specification limit(s).
A numeric value or a numeric vector of length 2 of the
adjusted (as specified by the sf_option parameter) specification
limit(s).
A numeric value or a numeric vector of length 2 of
the adjusted and transformed, if applicable (as specified by the the
sf_option parameter and the second element of the xform
parameter, respectively) specification limit(s), otherwise the same as
sl.
A numeric value or a numeric vector of length 2 that
specifies the specification limit or limits. If a vector is provided it
must be of the form c(lower limit, upper limit).
A positive integer or a vector of positive integers that
specifies the number of “significant figures” (sf) of sl.
It must have the same length as sl.
A character string that specifies if the limits (rl
or sl) should be regarded as “tight” or “loose”, i.e.
either "tight" or "loose", respectively. The default is
"tight". The option "tight" means that the limits are
rounded to the number of significant digits specified by the parameters
rl_sf and sl_sf. If sf_option = "loose", four on
the order of the last significant digit + 1 is added if
ivl_side = "upper" or five on the order of the last significant
digit + 1 is subtracted if ivl_side = "upper".
A vector of two character strings that specifies the
transformation of the response and the time variable. The default is
“no” transformation, i.e. c("no", "no"), where the first
element specifies the transformation of the \(x\) variable and the
second element the transformation of the \(y\) variable. Valid
alternatives for \(x\) and/or \(y\) variable transformation are
"log" (natural logarithm), "sqrt" (square root) and
"sq" (square).
A vector of two values which will be added to the variables
\(x\) and/or \(y\) before they are transformed as specified by the
xform parameter, where the first element will be added to the
\(x\) variable and the second element to the \(y\) variable. The
purpose is to prevent an undefined state which could arise when variables
with values of \(\leq 0\) are log or square root transformed. The
default is c(0, 0).
A character string that specifies if the specification
limit, given that the limit has only one side, is an “upper” or a
“lower” bound, i.e. it is specified as either "upper" or
"lower", respectively. The default is "lower". If the
specification has two boundaries, then this parameter specifies the
preferred side. If no side is preferred over the other, "both" can
be used.
The function set_limits() adjusts the limits according to
rl_sf and sl_sf and, if necessary, transforms the limits
(rl and sl) as specified by the parameters xform and
shift.
