redatamx

About

redatamx is a package to work with REDATAM databases in RXDB (new) or DICX (old) format.

Installation

To install the R package, run the following command:

# Install released version from CRAN
install.packages("redatamx")

Usage

The Redatam package enables the use of REDATAM databases inside R. It is possible to open a REDATAM dictionary (dicx format or the new rxdb format) and run Redatam programs written in SPC language.

For example:

library(redatamx)

# open a dictionary
dic<-redatam_open("path/to/nmir.rxdb")

# run a frequency using the new syntax
tbl1<-redatam_query(dic, "freq person.sexo")

#-- you can use the old syntax too
#-- tbl1<-redatam_query(dic, "table t1 as frequency person.sexo")

print(tbl1)

# close the dictionary
redatam_close(dic)

You need to replace path/to/nmir.rxdb to point to your NMIR dictionary (Redatam database).

After running the above program, you will find a new data frame tbl1 that corresponds to the output of the REDATAM program. You can use R commands to operate with the new data frame, the output of the above program is:

##  SEXO1_value SEXO1_label  value
##            1      Hombre  26834
##            2       Mujer  25355

Plugins

You can use custom plugins:

  • Datasources: custom formats for database creation
  • Exporters: custom formats for exporting the outputs (tables) of SPC queries

You can check the available plugins using redatam_info() function:
