Summary data for hemispherical camera data.

fd_hemi_camera_summary()

Value

A data.frame or tibble. See "Details" for column descriptions.

Details

The columns are as follows:

  • replicate (character): Replicate code, extracted from SubplotID.

  • plot (integer): Plot ID number, extracted from SubplotID.

  • subplot (character): Subplot code, extracted from SubplotID.

  • date (date): Date of measurement

  • lai_cam (numeric): mean of leaf area index

  • lai_cam_sd (numeric): sd of leaf area index

  • lai_cam_n (integer): number of observations per sample

  • lai_cam_se (numeric): se of leaf area index

  • ndvi (numeric): mean of plot ndvi

  • ndvi_sd (numeric): sd of plot ndvi

  • ndvi_n (numeric): number of observations per sample

  • ndvi_se (numeric): se of plot ndvi

Note

For now this is pretty basic. More detailed summaries could be made, e.g. by live/dead, species, etc.
