How to load a CSV txt file into R correctly

问题

I'm very new to R, and having some simple trouble. I thought I understood the read.table() function, but apparently not. I'm trying to load "http://www.stat.berkeley.edu/users/nolan/data/bikeshare.txt" into RStudio, and for whatever reason, it only displays the text file again. My command was:

read.table("http://www.stat.berkeley.edu/users/nolan/data/bikeshare.txt",
           sep=",", 
           header=True)

Any help is much appreciated.

Thanks.

Here is an example:

Code Example:

URL <- "http://www.stat.berkeley.edu/users/nolan/data/bikeshare.txt"
bikeshare <- read.table(URL, sep=",", header=TRUE)
head(bikeshare)

Example Output:

> URL <- "http://www.stat.berkeley.edu/users/nolan/data/bikeshare.txt"
> bikeshare <- read.table(URL, sep=",", header=TRUE)
> head(bikeshare)
