dssSuggestPivot: Suggest a formula for widening a dataframe
In IulianD/dsSwissKnifeClient: DataSHIELD Tools and Utilities - client side

Makes a crude attempt at guessing an appropriate widening formula to feed into dssPivot. The method is pretty basic, it should serve more as a starting point for further investigation

dssSuggestPivot(
  what,
  cols = NULL,
  by.col = NULL,
  async = TRUE,
  wait = TRUE,
  datasources = NULL
)

`what`	a character name of the dataframe
`cols`	a vector of columns used in the formula. They must exist in 'what'. If null, all the columns from 'what' will be used.
`by.col`	typically the patient id, the column that will end up as key of the resulting 'wide' data.frame.
`async`	a logical, see datashield.aggregate
`wait`	a logical, see datashield.aggregate
`datasources`	a list of opal objects obtained after logging into the opal servers (see datashield.login)
