Detailed information about a database table and its classification on the open-data API which is supported by National Statistical Office of Mongolia (NSO)

1	get_table_info(tbl_id, simplify = FALSE, try = FALSE, timeout = Inf)

`tbl_id`	character string, Table identification number
`simplify`	logical: Should the result be simplified to a vector and a data frame?
`try`	logical: Should the body of the function be wrapped by the function `try`? See details.
`timeout`	positive numeric or `Inf`: The number of seconds to wait for a response from the NSO server. Can not be less than 1 ms or 0.001 s.

The NSO server returns "HTTP error 500" frequently. Due to the server error, error handling is supported. if try is TRUE, you have to write code with error handling as shown in the example.

A list which contains information about database table and its classification if the function is executed without error, but an object of class "try-error" containing the error message, if it fails. The list has following structure:

tbl_id

Table identification number

unit_id

Unit identification number

unit_nm

Unit name in Mongolia

unit_eng_nm

Unit name in English

obj

Table classification:

obj_var_id

Variable identification

var_ord_sn

Variable identification number

field

Field name

scr_mn

Variable name in Mongolian

scr_eng

Variable identification

itm

Variable classification and code:

itm_id: Classification number
up_itm_id: Sub-classification
scr_mn: Classification name in Mongolian
scr_eng: Classification name in English

if simplify is TRUE, an user-friendly result is returned.
