This vignette describes the process of converting a string representation of a CHOIR Body Map (CBM) into a plot.
CBM data for a given patient is often provided in a delimited string similar to this: “101,102,103,104” (these segment identifiers indicate the face and top of the head). If you want to plot the CBM of a single patient (e.g., for a report) or highlight specific segments on a CBM (e.g., in a paper), then you can use the
string_to_map function to convert this string into an R
data.frame object ready for the rest of the plotting functions in
CHOIRBM. Let’s take the above string as an example.
Start with the string representation of a patient’s CBM. When it is converted to a data frame, the CBM is represented as a series of segment IDs with a group label (indicating if the segment belongs to the front or back of the body map) and a binary value to indicate whether the segment was present in this patient’s CBM string.
library(CHOIRBM) <- "101,102,103,104" cbm_str <- string_to_map(cbm_str) cbm_df head(cbm_df) #> id group value #> 1 101 Front 1 #> 2 102 Front 1 #> 3 103 Front 1 #> 4 104 Front 1 #> 5 105 Front 0 #> 6 106 Front 0
The resulting data frame is plot-able:
