How do I import a survey into R Studio from an internet address?

[BubblesAreUs]

I am using R studio for a practical and I need to load a survey. It suggests that I place the following into the R template that I was provided:

survey=read.csv("http://www.maths.usyd.edu.au/u/UG/IM/STAT2012/r/survey.csv")
attach(survey)
pulse.sf=pulse[smoke==1 & sex==2]
pulse.sf

Template link http://www.maths.usyd.edu.au/u/UG/IM/STAT2012/r/p4.Rnw.

I have no clue WHERE one inserts these lines. I try the following:

urvey <- read.csv(file="http://www.maths.usyd.edu.au/u/UG/IM/STAT2012/r/survey.csv")
attach(survey)
$Error in attach(survey): object ’survey’ not found pulse.sf=pulse[smoke==1 & sex==2]$ Error in eval(expr, envir, enclos): object ’pulse’ not found
pulse.sf
## Error in eval(expr, envir, enclos): object ’pulse.sf’ not
foun

What's going on? I can actually download the survey and view it on Excel. The problem is drawing the data into R studio.

Appreciate any help that I can get.

It works for me. So some questions:
1) Did you actually download the survey and put it in your computer?
2) What folder did you put in the survey? Type getwd() in R to see what folder you should put in the survey. For example if getwd() yields C:\Documents, then you should put the csv file in that folder and then access it by survey <- read.csv("survey.csv")
3) You can change your folder in R by setwd https://stat.ethz.ch/R-manual/R-devel/library/base/html/getwd.html

@micromass is right. You have to have the file on your computer. You can not read it from an internet address.
