Lab 05: R Data Type Summary

Note

In lab.qmd Lab 5,

• Create R objects vector v1, factor f2, list l3, matrix m4 and data frame d5.

• Check typeof() and class() of those objects, and create a list having the output below.

v1 <- __________
f2 <- __________
l3 <- __________
m4 <- __________
d5 <- __________
v <- c(type = typeof(v1), class = class(v1))
f <- c(type = __________, class = _________)
l <- c(type = __________, class = _________)
m <- c(type = __________, class = _________)
d <- c(type = __________, class = _________)
____(vec    =   v,
     ______ = ___,
     ______ = ___,
     ______ = ___,
     ______ = ___)
