flowchart 0.1.0

flowchart 0.2.0

Added new N= argument in functions as_fc(), fc_filter() and fc_split() to enter the number of rows manually in case that a dataframe is not available.
New fc_export() function to export a flowchart in the desired format.
Solved bug when performing a split. Now the x-coordinates of the resulting boxes are placed symmetrically around the parent box, not homogeneously distributed across all the space.

Added round_digits= argument to fc_filter() and fc_split() functions, which allows to change the number of decimals to round percentages.
Added show_zero= argument to fc_split(), which allows to control whether the groups with zero events should be shown in a box or not.
Updated description with minimum R version (>= 4.1.0).

Bug in the fc_split() function when splitting by a factor with levels that are not arranged in alphabetical order.
Bug in the fc_split() function when performing multiple splits and showing percentages. These percentages were calculated based on the total number of rows, not the total number of rows in each of the groups defined by the previous splits.

New arguments text_fface, text_ffamily and text_padding to change the font face, font family and padding of the text inside the box
New argument perc_total to calculate percentages with respect to the total number of rows
New argument offset to add space to the distance between boxes in a split, and offset_exc to add space to the distance from the exclude box in a filter
New function fc_view() to view the $fc element or the $data element, associated to a flowchart
New argument title in the fc_draw() function to add a title to a flowchart, along with some additional arguments to customize it
New argument title in the fc_split() function to add a title box in a split, together with some additional arguments to customize it
Bug in the exclusion box out of margins

Added box_corners argument to fc_draw() to allow drawing boxes with or without round corners; default set to "round" to avoid breaking changes (#2; @kenkomodo)
Updated fc_export() to include vector formats (svg, pdf) and to use ragg in place of grDevices for relevant bitmap formats (png, jpeg, tiff) for improved performance and image quality when ragg is installed (#16; @kenkomodo)
Methods for S3 class fc correctly defined
Bug in the hide = TRUE option in as_fc()
Bug when specifying sel_group and N at the same time in fc_split()
Bug when specifying title in fc_split() with a number of splits different than two

Solved bug when sel_group is used repeatedly in the same flowchart
Changed y-coordinate distribution of boxes when using fc_stack() with unite = TRUE
When performing multiple splits in a flowchart, the group label is stored in $fc concatenating the values of the different groups separated by ‘//’
Allow expressions in the label argument to produce bold or italics text, or even formulas

Solved bug when perc_total = TRUE is used together with show_exc = TRUE.
Solved bug when applying fc_filter() in a box with missing values.
Added big.mark argument to fc_draw() to allow users to insert a thousands separator for values of n and N printed in flowchart boxes (e.g., big.mark = "," results in "1,000") (#26; @kenkomodo)
Updated package functions to throw warnings using cli; added dependency on cli (@kenkomodo)
Added test suite for package functions (@kenkomodo)
Updated fc_draw() with canvas_bg argument which allows the user to specify the flowchart canvas background color or to set it to "transparent" (#30; @kenkomodo)
Updated fc_export() to accept the new canvas_bg argument from fc_draw() and apply it accordingly to the exported flowchart image (#30; @kenkomodo)
Solved bug causing fc_export() to drop newer fc_draw() arguments when redrawing the flowchart for export (#32; @kenkomodo)
New width and height arguments for as_fc(), fc_filter() and fc_split() functions to manually set the size of boxes.
