MotionImports <- gvisMotionChart(Imports, + idvar="PTP", + timevar="Ref_Date") Error in gvisMotionChart(Imports, idvar = "PTP", timevar = "Ref_Date"): could not find function "gvisMotionChart" plot(MotionImports)

It keeps showing an error whenever I try to troubleshoot or do a diagnostic.

Answer 1

It looks like you need to try the following.

# Install Rtools and googleVis
install.packages(c("Rtools", "googleVis"))

# Load googleVis
library(googleVis)

You might also want to save your script in the same folder as your local data, and then change the working directory to that folder. You can do this in RStudio using:

Session > Set Working Directory > To Source File Location

After that, you can try importing the data as usual.
