Find Location and Character Vector of an Object with partial name in R Language – apropos() and find() Function

  • Last Updated : 23 Dec, 2021

In this article, we are going to find the location and character vector of an object with a partial name in R Programming Language.

R – apropos() Function

appros() function in R Language will give the character vector of name that contains the partial name.

Syntax: apropos(“x”, ignore.case, simple.word)

Parameters: 

  • x: partial-name of object
  • ignore.case: Case sensitive or not
  • simple.word: if TRUE the what is searched as a whole word

Example:

R




# R program to illustrate
# appros function
 
# Apply apropos function in R
apropos("max", ignore.case = FALSE, simple.word = FALSE)               

Output: 

“cummax”    “max”     “max.col”   “pmax”      “promax”    “varimax”   “which.max”

Here in the above code, the appros() function will return all the strings which have “max” in them.

R – find() Function

find() Function in R returns the location where the object with specific name can be found.

Syntax: find(“x”, ignore.case, simple.word)

Parameters: 

  • x: partial-name of object
  • ignore.case: Case sensitive or not
  • simple.word: if TRUE the what is searched as a whole word

Example:

R




# R program to illustrate
# find function
 
# Apply find function in R
find("varimax", ignore.case = FALSE, simple.word = FALSE)               

Output: 

# "package:stats

Here in the above code, we get the location of where “varimax” is stored. So find() function is used to find what we have specified to it.
