Description

Hi, I encounter a problem in livy-interpreter for sparkr, the output objet are not display if we don't make a direct call with plot for example

{{

%livy.sparkr

library(ggplot2)
pres_rating <- data.frame(
rating = as.numeric(presidents),
year = as.numeric(floor(time(presidents))),
quarter = as.numeric(cycle(presidents))
)
p <- ggplot(pres_rating, aes(x=year, y=quarter, fill=rating))
p <- p + geom_raster()

p

}}

render png2 (image livy_spark_error_01.PNG)

but
 

{{

%livy.sparkr

library(ggplot2)
pres_rating <- data.frame(
rating = as.numeric(presidents),
year = as.numeric(floor(time(presidents))),
quarter = as.numeric(cycle(presidents))
)
p <- ggplot(pres_rating, aes(x=year, y=quarter, fill=rating))
p <- p + geom_raster()

plot(p)

}}

work fine (image livy_spark_error_02.PNG)

 

it is not that important but due to that impossible to render functions like pairs or any plotly object
