Aggregate the contents in ../measured-values by sh ./aggregate.sh
first.
Invoke R and install the following packages if not done previously:
install.packages("TTR")
install.packages("lubridate")
# installation of tidyverse takes a long time
install.packages("tidyverse")
Run the following code for generating PNG graphs and fldigi-compatible data:
source("./builddata.R")
source("./dateplot.R")
source("./pswsdata.R")
- Smooth the data by 20-second averaging
- Build the functions by the measured data of frequency and amplitude so that the estimated values by interpolation can be obtained for a given timing in UNIX/POSIX epoch
- dateplot.R: plot the data on a PNG file
- pswsdata.R: output the fldigi-and-PSWS-compatible estimated data so that the processing scripts for fldigi and PSWS data can be applied later
