Scatter plot server function

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 expects, 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 expects to contain, at least, subjid_var

Usage

scatterplot_server(
  id,
  bm_dataset,
  group_dataset,
  dataset_name = shiny::reactive(character(0)),
  cat_var = "PARCAT",
  par_var = "PARAM",
  value_vars = "AVAL",
  visit_var = "AVISIT",
  subjid_var = "USUBJID",
  default_x_cat = NULL,
  default_x_par = NULL,
  default_x_value = NULL,
  default_x_visit = NULL,
  default_y_cat = NULL,
  default_y_par = NULL,
  default_y_value = NULL,
  default_y_visit = NULL,
  default_group = NULL,
  default_color = NULL,
  compute_lm_cor_fn = sp_compute_lm_cor_default
)
