swimmer_plot: Creating the base of a swimmers plot

Description

This function allows you to create swimmers plots with bars, includes options to have the bars change colours and create stratified plots

Usage

swimmer_plot(
  df,
  id = "id",
  end = "end",
  start = "start",
  name_fill = NULL,
  name_col = NULL,
  name_alpha = NULL,
  increasing = TRUE,
  id_order = NULL,
  stratify = FALSE,
  base_size = 11,
  identifiers = TRUE,
  ...
)

Arguments

df

a data frame

id

column name for id, default is 'id'

end

column name with the bar lengths (or bar end positions if bars change colour), default is 'end'

start

column name with the bar start positions (only required when there are gaps between sections of bars, or bars which do not start at zero), default is 'start'

name_fill

a column name to map the bar fill

name_col

a column name to map the bar colour

name_alpha

a column name to map the bar transparency

increasing

Binary to specify bars in increasing order (Default is TRUE)

id_order

order of the bars by id, can input a column name to sort by, or the ids in order.

stratify

a list of column names to stratify by

base_size

the base size for the plot, default is 11

identifiers

Binary to specify patient identifiers are included in the y axis (default is TRUE)

...

additional geom_col() arguments

Value

a swimmer plot with bars

Examples

# NOT RUN {



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

# Add ggplot layers to improve the plot's aesthetic

swim_plot +
ggplot2::scale_fill_manual(name="Treatment",values=c("#e41a1c", "#377eb8","#4daf4a"))+
ggplot2::ylab('Time (Days)')



#Example with Stratification

swim_plot_stratify <- swimmer_plot(df=ClinicalTrial.Arm,id='id',end='End_trt',name_fill='Arm',
col="black",alpha=0.75,width=.8,base_size = 18,stratify= c('Age','Sex'))

swim_plot_stratify +
ggplot2::scale_fill_manual(name="Treatment",values=c("#e41a1c", "#377eb8","#4daf4a"))+
ggplot2::ylab('Time (Days)')

#Example when there are gaps between the bars and bars do not start at zero

#Both a start and end time need to be specified when there are gaps between sections of bars

Gap_data <- data.frame(patient_ID=c('ID:3','ID:1','ID:1','ID:1','ID:2',
                                   'ID:2','ID:2','ID:3','ID:3','ID:2'),
                      start=c(10,1,2,7,2,10,14,5,0,22),
                      end=c(20,2,4,10,7,14,22,7,3,26),
                      treatment=c("A","B","C","A","A","C","A","B","C",NA))

swimmer_plot(df=Gap_data,id='patient_ID',name_fill="treatment",col=1,identifiers=FALSE,
id_order = c('ID:1','ID:2','ID:3')) +
ggplot2::theme_bw()+ggplot2::scale_fill_manual(name="Treatment",
values=c("A"="#e41a1c", "B"="#377eb8","C"="#4daf4a",na.value=NA),breaks=c("A","B","C"))+
