swimmer_points_from_lines {swimplot}

Adding points to a swimmers plot which match up with lines

Description

This function will create points at the beginning and end of line to match with swimmer_lines.

Usage

swimmer_points_from_lines(
  df_lines,
  id = "id",
  start = "start",
  end = "end",
  cont = NULL,
  adj.y = 0,
  name_shape = "type",
  name_col = NULL,
  name_size = NULL,
  name_fill = NULL,
  name_stroke = NULL,
  name_alpha = NULL,
  ...
)

Arguments

df_lines

a data frame

id

column name for id, default is 'id'

start

column name where the line starts, default is 'start'

end

column name where the line ends, default is 'end'

cont

a column name of which lines continue (NA is does not continue) these will not have a point at the end of the line

adj.y

amount to adjust the point within the box vertically (default is 0, point is in the centre of each bar)

name_shape

a column name to map the point shape

name_col

a column name to map the point colour

name_size

a column name to map the point size

name_fill

a column name to map the point fill

name_stroke

a column name to map the point stroke

name_alpha

a column name to map the point transparency

...

additional geom_point() arguments

Value

a swimmer plot with points matching the lines

Examples

#Start with a base swimmer plot


swim_plot <-swimmer_plot(df=ClinicalTrial.Arm,id='id',end='End_trt',name_fill='Arm',col="black"
,id_order= 'Arm')


# Then add lines to the plot

swim_plot_with_lines <- swim_plot +
swimmer_lines(df_lines=ClinicalTrial.Response,id='id',start =
'Response_start',end='Response_end',name_col='Response',size=3)

# Add points to the start and end of the lines

swim_plot_with_lines_and_points <- swim_plot_with_lines+
swimmer_points_from_lines(df_lines=ClinicalTrial.Response,id='id',start =
'Response_start',end = 'Response_end', cont =
'Continued_response',name_col='Response',size=4)

# Add ggplot layers to improve the plot's aesthetic
