Matrix of scatterplots module

mod_scatterplotmatrix is a Shiny module prepared to display data in a matrix of scatterplots with different levels of grouping. It also includes correlation stats.

Input dataframes:

bm_dataset

It expects a dataset similar to https://www.cdisc.org/kb/examples/adam-basic-data-structure-bds-using-paramcd-80288192 , 1 record per subject per parameter per analysis visit.

It must contain, at least, the columns passed in the parameters, subjid_var, cat_var, par_var, visit_var and value_var. The values of these variables are as described in the CDISC standard for the variables USUBJID, PARCAT, PARAM, AVISIT and AVAL.

group_dataset

It expects a dataset with an structure similar to https://www.cdisc.org/kb/examples/adam-subject-level-analysis-adsl-dataset-80283806 , one record per subject.

It must contain, at least, the column passed in the parameter, subjid_var.

Usage

scatterplotmatrix_UI(id)

scatterplotmatrix_server(
  id,
  bm_dataset,
  group_dataset,
  dataset_name = shiny::reactive(character(0)),
  cat_var = "PARCAT",
  par_var = "PARAM",
  value_vars = c("AVAL", "PCHG"),
  visit_var = "AVISIT",
  subjid_var = "SUBJID",
  default_cat = NULL,
  default_par = NULL,
  default_visit = NULL,
  default_value = NULL,
  default_main_group = NULL
)

mod_scatterplotmatrix(
  module_id,
