1. Go to http://www.macromedia.com/support/documentation/en/flashplayer/

help/settings_manager04.html

2. Click on the dropbox which says ’Edit location’ and choose ’add location’

3. Click ’browse for folder’

4. Choose the folder in which you saved your html ﬁle

5. Click OK

Now op en your googleVis html ﬁle and it should display successfully.

Alternatively use the function plot.gvis explicitly, e.g. suppose your html ﬁle

is stored in /Users/JoeBloggs/myGoogleVisChart.html. Using the plot.gvis

the ﬁle will be copied into a te mporary directory and displayed via the R HTTP help

server with, in the same way as a gvis-object:

R> plot.gvis("/Users/JoeBloggs/myGoogleVisChart.html")

Please note that this feature of plot.gvis was intro duced to googleVis with

version 0.3.2.

2.5 Setting default behaviour of print.gvis and plot.gvis

In googleVis version 0.3.2 the function plot.gvis gained the same argument as

print.gvis: tag. By default the tag argument is set to NULL in plot.gvis and

the plot function will display its output in a browser window. However, if tag is

not NULL the function plot.gvis will behave exactly like print.gvis.

The default tag can be set for both functions globally via the options() func-

tion. On package load googleVis sets options(gvis.print.tag=’html’) and

options(gvis.plot.tag=NULL).

Suppose you would set options(gvis.plot.tag=’chart’) then all following plot

statements would print the chart part of the gvis-object only, without opening a

browser window. This might seem a bit odd at ﬁrst, yet it becomes helpful when

you write R Markdown ﬁles for knitr or ﬁles for other packages such as R.rsp.

While you draft your ﬁle you may want to see the output of googleVis in an

interactive way, so you set options(gvis.plot.tag=NULL) at the top of the ﬁle

and you change the setting to ’chart’ before you parse the ﬁle, say with knitr.

This will ensure that all plot statements return the HTML code of the chart, rather

than opening browser windows. Section 4 on page 32 provides more details and a

little knitr example.
