I am trying to run a low pass filter on 1000Hz sampled data to 100Hz. Currently data is saved in csv file with a name of data on first row (Time, Measured value etc).
I have imported this data in R studio to variable name "data1"
I would like to run low pass filter and I have done some search on this. I have found several packages and tried to use "butterworth" function. However, I am having an issue on variable of function. Is there any way to run low pass filter by using csv file itself? (Instead of modifying csv file in R studio?)
