Usually you will obtain a data frame by importing it from SAS , SPSS , Excel , Stata, a database, or an ASCII file. To create it interactively, you can do something like the following.
# create a data frame from scratch
age <- c(25,30,56)
gender <- c("male","female","male")
weight <- c(160,110,220)
mydata <- data.frame(age,gender,weight)संचालित द्वारा
You can also use R's built in spreadsheet to enter the data interactively, as in the following example.
# enter data using editor
mydata <- data.frame(age=numeric(0), gender=character(0), weight=numeric(0))
mydata <- edit(mydata)# note that without the assignment in the line above,# the edits are not saved!संचालित द्वारा
