Read and combine processed data products

Reads and combines data files processed with this package(e.g., time series, cleaned remote sensing index, or phenological metrics). Supports reading a subset of data from specified sites and groups. Three data products are supported:

• "ts": raw time series data

• "clean": cleaned time series data, with optionally calculated Enhanced Vegetation Index (EVI)

• "doy": extracted phenological metrics

Usage

read_data_product(dir, v_site = NULL, v_group = NULL, product_type = "clean")

Arguments

dir

Character. Base directory containing processed data product files (e.g., the parent directory of "ts/", "clean/", or "doy/").

v_site

Character vector, optional. Site identifiers to include; if NULL, all sites are included.

v_group

Character vector, optional. Group identifiers to include; if NULL, all groups are included.

product_type

Character. Type of product to read (e.g., "ts", "clean", or "doy"). Default is "clean".

Value

A data frame combining all matching data product files, with columns for site and group.

Examples

if (FALSE) { # \dontrun{
# Example: Read all cleaned time series for two sites and one group
df_clean <- read_data_product(
  dir = "alldata/PSdata/",
  v_site = c("HARV", "SJER"),
  v_group = "Quercus",
  product_type = "clean"
)

# Example: Read all phenological metrics for a site
df_doy <- read_data_product(
  dir = "alldata/PSdata/",
  v_site = "SJER",
  product_type = "doy"
)
} # }
