Introduction

the first stp in data analayis R software

getwd()

getwd()
## [1] "C:/Users/hp/OneDrive/Desktop"

Then read data SPSS WE need haven package

setwd("C:/Users/hp/OneDrive/Desktop/R-Training")
library(haven)
sleepdata=read_sav("sleep.sav")
dim(sleepdata)
## [1] 271  55
names(sleepdata)
##  [1] "id"           "sex"          "age"          "marital"      "edlevel"     
##  [6] "weight"       "height"       "healthrate"   "fitrate"      "weightrate"  
## [11] "smoke"        "smokenum"     "alchohol"     "caffeine"     "hourwnit"

par(mfrow=c(1,2))
tabsex=table(sleepdata$sex)
tabsex

Objective

R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.

When you click the Knit button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

dim(cars)
## [1] 50  2
summary(cars)
##      speed           dist       
##  Min.   : 4.0   Min.   :  2.00  
##  1st Qu.:12.0   1st Qu.: 26.00  
##  Median :15.0   Median : 36.00  
##  Mean   :15.4   Mean   : 42.98  
##  3rd Qu.:19.0   3rd Qu.: 56.00  
##  Max.   :25.0   Max.   :120.00

Including Plots

You can also embed plots, for example:

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.
