SPSS to R

Build Status codecov.io

A set of functions that takes SPSS syntax as input and outputs R commands to do the same analysis or data management tasks.

Current Features

  • Read in Data
    • Get for sav files
    • Get for csv, txt, xls, xlsx files with get data.
  • Data Manipulation
    • Sort Cases
  • Descriptives
    • Aggregate
    • Correlations
    • Crosstab
    • Descriptives
    • Frequencies
    • Graphics
  • Models
    • One sample t-test
    • Independent sample t-test
    • One-way ANOVA - with oneway routine

Upcoming Features

  • Dataset commands
  • Value Labels
  • Further arguments for descriptives
  • Modeling functions
    • t-test (two sample with cut score and paired)
    • analysis of variance - more complicated designs
    • regression
    • generalized models
  • if else statements
  • Examine

Installing Function

devtools::install_github("lebebr01/SPSStoR")
library(SPSStoR)

Examples

Multiple commands


# Multiple commands in one
spss_to_r(system.file("SPSSsyntax", "getDescExamp.txt", package = "SPSStoR"))
## # x is the name of your data frame
## library(foreign)
## x <- read.spss('/data/hubtemp.sav', to.data.frame = TRUE)

## temp <- x[, list(age_mean=mean(age), age_median=median(age), income_median=median(income)), ]
## x[, age_mean:=mean(age), ]
## x[, age_median:=median(age), ]
## x[, income_median:=median(income), ]
## x[order(gender, marital), age_mean:=mean(age), by = list(gender, marital)]
