all_names_present

dataset where the variable names should be found

data

a character vector of variable names, e.g.
<code>c("var1", "var2")</code>

var.names

stops

Custom message to return instead of default message.
Special: include <code>%%VARS%%</code> in message string and the missing 
variable names will be inserted there (quoted, separated by comma, e.g. 
<code>'var1'</code>, <code>'var2'</code> --- no leading or tracing white space).

Given a character vector, checks if all names are present in <code>names(data)</code>.
Throws error if <code>stops=TRUE</code>, else returns <code>FALSE</code> if some variable name is not present.

Enables computation of epidemiological statistics where e.g.
counts or mortality rates of the reference population are used. Currently
supported: excess hazard models, rates, mean survival times, relative
survival, as well as standardized incidence and mortality ratios (SIRs/SMRs),
all of which can be easily adjusted for e.g. age.
Fast splitting and aggregation of 'Lexis' objects (from package 'Epi')
and other computations achieved using 'data.table'.

all_names_present: Check if all names are present in given data
