markdown - add local image file in R presentation -

-

i'm trying include 1 imaging file (.png) using r markdown r presentation. followed suggestion from: how import local image using knitr markdown using ![title](my.png), error:

error: unexpected '[' in "!["

the my.png file in current path. tried using absolute path got same error message.

putting above inside r chuck failed too.

i tried 

```{r,fig.width=350, fig.height=250,echo=false} library(png) library(grid) appimg <- readpng('my.png') grid.raster(appimg) ```

but failed too!

i working on windows 7 r studio 0.98.1102 , r 3.2.1 .

after huge mount of google search. finanlly figure out problem.

the key html cannot refer local file security reason. except local html file, can refer local file in same file directory.

and r presentation html file webpage.

so, put image file same directory html file, things work. @ least worked me.

just use

![some caption](img_file_name.png)

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...
