In FIESTA: Forest Inventory Estimation and Analysis

Data - Get frequency table for specified variable(s).

Description

Generates a frequency table from a data frame, including number of records by a specified variable or variables in the data frame with optional totals and/or subtotals.

Usage

datFreq(
  x,
  xvar = NULL,
  total = FALSE,
  subtotal = FALSE,
  subtotalcol = NULL,
  savedata = FALSE,
  savedata_opts = NULL,
  gui = FALSE
)

Arguments

x	Data frame or comma-delimited file (*.csv). The table with the variable(s).
xvar	String (vector).* The name of the variable(s) to summarize.
total	Logical. If TRUE, a row is added to bottom of table with a total for the whole table.
subtotal	Logical. If TRUE, a row is added to bottom of each section for subtotals.
subtotalcol	Logical. If subtotal=TRUE, the column(s) to generate subtotals.
savedata	Logical. If TRUE, writes output data to outfolder.
savedata_opts	List. See help(savedata_options()) for a list of options. Only used when savedata = TRUE. If out_layer = NULL, default = 'datfreq'.
gui	Logical. If TRUE, pop-up windows will appear for user-interface.

Details

If no parameters, then user is prompted for input. If partial parameters, default parameter values are used.

Value

freqtable

Data frame. The frequency table.

If savedata=TRUE, a comma-delimited file of the frequency table is written to the outfolder.

Examples

# Set up data for example
tab <- data.frame(cbind(CONDCLASS = c(1, 1, 2, 1, 3, 3, 3, 1, 1, 1, 2, 1), 
		                     FORTYPCD = c(182, 184, 201, 221, 221, 184, 221, 182,
		                                  182, 201, 182, 221)))

# Frequency table with "FORTYPCD"       
datFreq(x = tab,
        xvar = "FORTYPCD")
		                                  
# Frequency table with "CONDCLASS" and "FORTYPCD" 		                                   
datFreq(x = tab,
        xvar = c("CONDCLASS", "FORTYPCD"))

# Frequency table with "CONDCLASS" and "FORTYPCD", adding total and subtotal
# rows 		                                   
datFreq(x = tab,
        xvar = c("CONDCLASS", "FORTYPCD"), 
        total = TRUE, 
        subtotal = TRUE)
        
# Frequency table for WYtree, multiple variables, subtotal options
datFreq(x = FIESTA::WYtree,
        xvar = c("SPGRPCD", "SPCD", "STATUSCD"), 
	       subtotal = TRUE, subtotalcol = "SPCD")
