ergm-errors: Sensible error and warning messages by 'ergm' initializers

In ergm: Fit, Simulate and Diagnose Exponential-Family Models for Networks

Sensible error and warning messages by ergm initializers

Description

These functions use traceback and pattern matching to find which ergm initializer caused the problem, and prepend this information to the specified message. They are not meant to be used by end-users, but may be useful to developers.

Usage

ergm_Init_abort(..., default.loc = NULL, call = NULL)

ergm_Init_stop(..., call. = FALSE, default.loc = NULL)

ergm_Init_warn(..., default.loc = NULL)

ergm_Init_warning(..., call. = FALSE, default.loc = NULL)

ergm_Init_inform(..., default.loc = NULL)

ergm_Init_message(..., default.loc = NULL)

ergm_Init_try(expr)

Arguments

...	Objects that can be coerced (via paste0()) into a character vector, concatenated into the message.
default.loc	Optional name for the source of the error, to be used if an initializer cannot be autodetected.
call., call	See stop() and abort() respectively; note the different defaults.
expr	Expression to be evaluated (in the caller's environment).

Functions

• ergm_Init_try(): A helper function that evaluates the specified expression in the caller's environment, passing any errors to ergm_Init_stop().

Note

At this time, the rlang analogues ergm_Init_stop(), ergm_Init_warning(), and ergm_Init_message() all concatenate their arguments like their base R counterparts. This may change in the future, and if you wish to retain their old behavior, please switch to their base R analogues ergm_Init_stop(), ergm_Init_warning(), and ergm_Init_message().
