compareSizeFreqs.ByYear.LongFormat: Plot multiple size frequencies for comparison by year.

In wStockhausen/tcsamCrabFisheryData: Functions to process ADFG fishery data for the Tanner crab assessment.

Description

Function to plot size frequencies by year for visual comparison.

Usage

compareSizeFreqs.ByYear.LongFormat(dfrs = NULL, n = 1, lbls = NULL,
  yCol = "year", zCol = "size", fCol = "frequency", norm = TRUE,
  alternate = FALSE, ylim = NULL, zlim = NULL, flim = NULL,
  samePlotScale = TRUE, vlines = c(127, 140), ltys = 1, lwd = 2,
  cols = c("blue", "green", "cyan", "magenta"), alpha = 0.5,
  pdfFile = NULL, plt.nc = 4, plt.nr = 5)

Arguments

dfrs	- list of dataframes w/ size frequencies to compare
n	- number of size frequency "types" to compare (ignored if dfrs is given)
lbls	- vector of labels for size frequency "types" to use in plot legend
yCol	- dataframe column name with year info
zCol	- dataframe column name with size info
fCol	- dataframe column name with frequency info
norm	- flag (T/F) to plot normalized size frequencies
alternate	- flag (T/F) to alternate positive/negative scales for frequencies
ylim	- range of years to plot (can be NULL)
zlim	- range of sizes to plot (can be NULL)
flim	- range for frequency scale on plot (can be NULL)
samePlotScale	- flag (T/F) to use same frequency scale for all plots
vlines	- sizes at which to plot vertical reference lines
ltys	- vector of line types to use to plot size freq.s
lwd	- line width for outlines of size freq.s
cols	- vector of colors to use to plot size freq.s
alpha	- transparency value (0-1) to use for areas
pdfFile	- name of output pdf file (or NULL, if none desired)
plt.nc	- number of columns per page in which to arrange plots for pdf output
plt.nr	- number of rows per page in which to arrage plots for pdf output

Details

Dataframes should be derived from "long" format csv files for annual size frequencies.

If 'dfrs' is NULL, then 'n' represents the number of size frequency files the user will be prompted to specify for the comparison.
