Build a character vector or list with adaptive string formatting

The rprintf function checks the given character vector or list and applies appropriate formatters that transform it from generic patterns to specific texts with variables and indices as placeholders replaced by a given set of values in correct formats.

Usage
rprintf(x, ...)
Arguments
x
The character vector or list to be transformed
...
The arguments that specify the set of values to be placed
Aliases
  • rprintf
Examples
## Not run: 
# #' # Format a single-entry character vector with sprintf mechanism
# rprintf('Hello, %s','world')
# rprintf('%s (%d years old)','Ken',24)
# rprintf('He is %d but has a height of %.1fcm',18,190)
# 
# # Format a single-entry character vector with variable mechanism
# rprintf('Hello, $name', name='world')
# rprintf('$name ($age years old)',name='Ken',age=24)
# rprintf('He is $age but has a height of $height:.2fcm',age=18,height=190)
# rprintf('$a, $b:.1f, $c:+.2f, $b, $a:.0f',a=1.56,b=2.34,c=3.78)
# 
# # Format a single-entry character vector with numbering mechanism
# rprintf('Hello, {1}', 'world')
# rprintf('{1} ({2} years old)','Ken',24)
# rprintf('He is {1} but has a height of {2:.2f}cm',18,190)
# rprintf('{1}, {2:.1f}, {3:+.2f}, {2}, {1:.0f}',1.56,2.34,3.78)
# rprintf('{2},{1}','x','y')
# 
# # This function also works for character vectors and lists.
# rprintf(c('%s:%d','$name:$age','{1}:{2}'),name='Ken',age=24)
# rprintf(c(a='%s:%d',b='$name:$age',c='{1}:{2}'),name='Ken',age=24)
# rprintf(list('%s:%d','$name:$age','{1}:{2}'),name='Ken',age=24)
# rprintf(list(a='%s:%d',b='$name:$age',c='{1}:{2}'),name='Ken',age=24)
# 
# # It also works with list argument for named variables.
# p <- list(name='Ken',age=24)
# rprintf('name: $name, age: $age',p)
# rprintf('name: {1}, age: {2}',p)
# 
# Note that when the list of arguments are given names,
# the variable names in format string should be modified.
# rprintf('name: $arg.name, age: $arg.age', arg = p)
# ## End(Not run)
