Retrieving data from survey in R Studio
Ulrik: you can absolutely read from a URL in read.csv() with that syntax. The error `## Error in attach(survey): object 'survey' not found` suggests that the OP mis-typed something in the `survey` name in the assignment from `read.csv()`. However, the OP has quite a bit more to be concerned about than the missing variable in the environment if their stats program is encouraging both no spaces between operators and the use of `attach()`.

I don't think you can read files into R like that. This answer http://stackoverflow.com/questions/3236651/read-data-from-internet on Stack Overflow tells you, you could use the RCurl package. Here are more examples on getting data from online sources https://www.r-bloggers.com/getting-data-from-an-online-source/ You could also just download the file manually and open it using read.scv Hope this helps, Ulrik On Thu, 18 Aug 2016 at 19:10 Barathan Roy Pinas < bpin3104 at uni.sydney.edu.au> wrote:
Hello,
I have been given a .csv file and it is not loading. This is what I did.
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 here<http://www.maths.usyd.edu.au/u/UG/IM/STAT2012/r/p4.
Rnw
.
I insert the file into the R commands section for question 1. Doing that produces the following below: survey <- 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 found What's going on? I can actually download the survey and view it on Excel. Appreciate any help that I can get. [[alternative HTML version deleted]]
