All:
So this is a followup to a prior question. I am running 0.9.0 built
2 days ago from source.
I can not run the IR interpreter because there is no version of it for R
3.6 and I can not downgrade R.
So in the straight %r interpreter I am trying to get plotting to work.
I am running on a secure server as a daemon under a zeppelin user .
The user has a home directory and permissions.
In the R tutorial the google vis paragraphs do not produce
any output:
%r
library(googleVis)
df=data.frame(country=c("US", "GB", "BR"),
val1=c(10,13,14),
val2=c(23,12,32))
Bar <- gvisBarChart(df)
print(Bar, tag = 'chart')
The straight plotting paragrahs:
%r
pairs(iris)
Product this error:
Error in value[[3L]](cond): could not open file
'figure/unnamed-chunk-1-1.png'
I have tried setting the working directory to the home dir and I can
view the
contents but get the same error.
I have looked through the source code and simply have no idea where this
process is running or where it is trying to write out the image
My end customer for this effort is really into R so the ability to
produce graphs in Zeppelin in R is critical.
I welcome ANY suggestion on how to demonstrate graphs/plots.
