Reshape dataset to wide format

Description

Reshape dataset to wide format

Usage

reshape_wide(
  df,
  case_id_var,
  time_id_var,
  timevar_max = 6,
  datsize = Inf,
  chunks = 10
)

Arguments

df	dataframe
case_id_var	String with name of ID variable indicating same patient. E.g. idvar="PUBCSNUM" for SEER data.
time_id_var	String with name of variable that indicates diagnosis per patient. E.g. timevar="SEQ_NUM" for SEER data.
timevar_max	Numeric; default 6. Maximum number of cases per id. All tumors > timevar_max will be deleted before reshaping.
datsize	Number of rows to be taken from df. This parameter is mainly for testing. Default is Inf so that df is fully processed.
chunks	Numeric; default 10. Technical parameter how the data is split during reshaping.

Value

df

Examples

data(us_second_cancer)

msSPChelpR::reshape_wide(us_second_cancer,
                         case_id_var = "fake_id", 
                         time_id_var = "SEQ_NUM", 
                         timevar_max = 2,
                         datsize = 10000)
