Data Description
-----------------------------------
The I-V curve data is used for MLEET (Module Level Exposure and Evaluation Test) project funded by DOE (Department of Energy). It was taken from some commercial brand full size PV (photovoltaic) module under dampheat + DML (Dynamic Mechanical Load) indoor accelerated test. Each I-V curve has about 3800 points.

Load data and run code to extract IV features 
------------------------------------------
```{r, message=FALSE, eval=TRUE}
library(ddiv)
data("IV_4K")
IVExtractResult(IV_4K)
```
Example output
--------------------------
The result for finding steps for example data "IV_4K", no changepoint identifying step is found.
