This function allows to filter the flowchart in function of a expression that returns a logic value that are defined in terms of the variables in the database. It will generate one box per group showing the number of rows of the group that matches the condition, and will retain only those rows in the data base.

Arguments
- object
fc object that we want to filter.
- filter
Expression that returns a logical value and are defined in terms of the variables in the data frame. The data base will be filtered by this expression, and it will create a box showing the number of rows satisfying this condition.
- N
Number of rows after the filter in case
filter
isNULL
.- label
Character or expression that will be the title of the box. By default it will be the evaluated condition.
- text_pattern
Character or expression defining the structure that will have the text in each of the boxes. It recognizes
label
,n
,N
andperc
within brackets. For default it is"{label}\n {n} ({perc}%)"
. Iftext_pattern
orlabel
is an expression, thelabel
is always placed at the beginning of the pattern, followed by a line break where the structure specified bytext_pattern
is placed.- perc_total
logical. Should percentages be calculated using the total number of rows at the beginning of the flowchart? Default is
FALSE
, meaning that they will be calculated using the number at the parent leaf.- show_exc
Logical value. If
TRUE
a box showing the number of excluded rows will be added to the flow chart.- direction_exc
One of
"left"
or"right"
indicating if the exclusion box goes into the left direction or in the right direction. By default is"right"
.- label_exc
Character or expression that will be the title of the added box showing the excluded patients. By default it will show "Excluded".
- text_pattern_exc
Character or expression defining the structure that will have the text in the exclude box. It recognizes
label
,n
,N
andperc
within brackets. For default it is"{label}\n {n} ({perc}%)"
. If text_pattern or label is an expression, the label is always placed at the beginning of the pattern, followed by a line break where the structure specified bytext_pattern_exc
is placed.- sel_group
Select the group in which to perform the filter. The default is
NULL
. Can only be used if the flowchart has previously been split. If the flowchart has more than one group, it can either be given the full name as it is stored in the$fc
component (separated by '\'), or it can be given as a vector with the names of each group to be selected.- round_digits
Number of digits to round percentages. It is 2 by default.
- trim_trailing_zeros
Logical value. If
TRUE
, allows trailing zeros after the decimal to be trimmed (default isFALSE
).- just
Justification for the text:
"left"
,"center"
or"right"
. Default is"center"
.- text_color

"black"
by default. See thecol
parameter for gpar.- text_fs

by default. See thefill
parameter for gpar.- border_color

NA
, it automatically adjusts to the content (default). Must be an object of class unit or a number between 0 and 1.- just_exc

"black"
by default. Seetext_color
.- text_fs_exc
Font size of the text of the exclude box. It is 6 by default. See
text_fs
.- text_fface_exc
Font face of the text of the exclude box. It is 1 by default. See the
fontface
parameter for gpar. Seetext_fface
.- text_ffamily_exc
Changes the font family of the text of the exclude box. Default is

This number has to be at least between 0 and 1 (plot limits) and the resulting x coordinate cannot exceed these plot limits. The default is
NULL
(no offset).- width_exc
