read_df_raw: Read in Raw Data from Dataframe

In SunsVoc: Constructing Suns-Voc from Outdoor Time-Series I-V Curves

Description

Given an imported datafram of Hbase-Formatted IV curve data, this function reads in the data, filters missing temperature data, and checks for a nonzero maximum power point, in case of power loss. It resets the timestamps based on the minimum timestamp, and filters Isc values for the tracer's accuracy. Finally, a n_period counter is added to the dataframe.

Usage

read_df_raw(df, tracer_accuracy, t_period)

Arguments

df	dataframe; the IV curve data to be filtered
tracer_accuracy	The accuracy of the IV tracer used. See the device's manual to find the exact value at which Isc readings are no longer accurate.
t_period	Data period for the Psuedo-IV curves. Addded as a column to the dataframe based on the timestamp. Use units of days, i.e. daily periods should have t_period 1, weekly periods should have t_period 7, etc.

Value

df_raw, a dataframe containing the raw IV curve data

Examples

df_test <- read_df_raw(df_wbw, 1, 7) # Weekly periods
df_test <- read_df_raw(df_wbw, 1, 1) # Daily periods
