dh.findVarsIndex R Documentation
Return return indices of column names in server-side dataframe
Description
Some DataSHIELD functions require column indices as parameters. This is
hqighly susceptable to breaking as changes in code will change the order of
variables. This function allows you to specify the names of columns and
returns their indices.
Usage
dh.findVarsIndex(df = NULL, vars = NULL, conns = NULL, checks = TRUE)
Arguments
df
Character specifying a server-side data frame.
vars
Character vector of columns within 'df' for which to return the
indices.
conns
DataSHIELD connections object.
checks
Logical; if TRUE checks are performed prior to running the
function. Default is TRUE.
Value
Client-side list of indices corresponding to 'vars', where the length
of the list corresponds to the number of cohorts included in 'conns'.
