Error in readOGR(dsn, layer) : could not find function "readOGR"

I am very new to R and so what does this mean? Does this tell me that I need to install some package named "ReadOGR"

I am following along using code written by someone else in an effort to generate a heat map. here is the current section to give some context. 

   setwd("C:/Users/Someone/Documents/R")
   dsn <- "cb_2017_us_state_20m.shp"
   layer <- "cb_2017_us_state_20m"
   cb5 = readOGR(dsn, layer)

Installed rgdal to no success. Tried library(rgdal) 

  library(rgdal)

Try:

setwd("C:/Users/Someone/Documents/R")
dsn <- "cb_2017_us_state_20m.shp"
cb5 = readOGR(dsn)

Also, you can find the original files here: https://www.census.gov/geo/maps-data/data/cbf/cbf_state.html. Maybe there are some extra info there you want to use. You have to use the one with .shp not the shp.xlm If you do not have it, download from the link above!!! It should work now, if not, happy to help you!
