Hi all,
I am trying to implement a custom plot in PBI, which runs 100% without issues in R on my machine, and am running into a lot of isses. I've originally created a data table for the data in R, but have exported it out as a csv file for PBI. My questions:
1) Is there a way for me to run my original data.table() script to make the data table in PBI? When I try that in the R script editor, I get the following error: "No image was created. The R code didn't reseult in the creation of any visuals. Make sure your R script results in a plot to the R default device."
This seems to imply that I need to go with my original approach of using the csv file?
2) I need to subset my data frame to make one layer at a time in ggplot2. In R this works, but when I run my R script in PBI I get errors. As an example, the code below works:
library(ggplot2)
ggplot() +
geom_line(aes(x = my_date, y = value, lty = variable),
col = 'lightblue',
size = 1.0,
data = dataset)
But when I add a subset to the data frame it doesn't work any more!
ggplot() +
geom_line(aes(x = my_date, y = value, lty = variable),
col = 'lightblue',
size = 1.0,
data = dataset[variable == "Plan"])
Here "Plan" is one level of my factor 'variable' (variable is the name of the column). I get an error as follows: "Error in '[.data.frame'[dataset, variable == "Plan"): object variable not found . Calls geom_line -> layer ->fortify -> [-> [data.frame...execution halted.
Can anyone provide some insight?
