使用knitr加载在github上传的URL Rdata

Question

I had been trying to load some data (Rdata) using knitr:

load(url("https://github.com/gualis91/teacherperception/blob/master/tp.Rdata?raw=true",method="curl"))

When I Knit to HTML, the next output is presented:

Error un parse(text = x, srcfile = src) : <text>:3:0: unexpected end of input 1: load(url("https://github.com/gualis91/teacherperception/blob/master/tp.Rdata?raw=true",method="curl") 2: Calls: <Anonymous> ... evaluate -> parse_all -> pase_all.character -> parse Execution halted

I'd tried to eliminate the "method", changing the "https" to "http", eliminating the "?raw=True" to access the archive and nothing seems to work. But when I run it as code in the console it seems to work just fine!

Answer 1

When I run your code in a regular R session I get

Error in url(" https://github.com/gualis91/teacherperception/blob/master/tp.Rdata?raw=true ", : unused argument (method = "curl")

Now, if I remove method='curl' it works.

And does so in within a example from knitr

knitr::knit(text ='```{r}
load(url("https://github.com/gualis91/teacherperception/blob/master/tp.Rdata?raw=true"))
head(tp)
```')
