Store historic data after each dataset refresh

Hi all,   I have been creating a KPI dashboard which is scheduled to run every day. The result of each KPI is something like:   a) how many data points have been loaded b) what time has it taken...

Dear all,

 

I understood that most likely using R is the only way how to achieve this. I have now played around and created the following R script which runs after I have pulled together my dataset:

 

# 'dataset' holds the input data for this script
require(gdata)
write.table(trim(dataset), file="//Client/C$/Users/S8937/temp/test012.csv", sep = ",", row.names = FALSE, col.names=FALSE, append = TRUE)
plot(dataset)

 

 

Unfortunately I do get the following stack trace. Any idea on how to fix this?

 

Error Message:
Object reference not set to an instance of an object.

Stack Trace:
