This function calculates the daily correlation values between the pm25_A, pm25_B, humidity, and temperature channels. One correlation value for each channel pair will be returned for each day.

SoH_correlation(pat = NULL, aggregationPeriod = "10 min")

Arguments

pat

PurpleAir Timeseries pat object.

aggregationPeriod

The period of time over which to aggregate the data. Recommended that this value is at least greater than 2 min in order to have complete pairs between the A and B channels. If there is not a complete pair, the function will return an for that day. The smaller the aggregation period, the longer this function will take to run. The default is set to "10 min" for this reason.

Examples

tbl <- example_pat %>% SoH_correlation(aggregationPeriod = "30 min") timeseriesTbl_multiPlot(tbl, ylim = c(-1,1), style = "line")
