  x.order = NULL,
  sevar = NULL,

  device.type = "dev.new",
  jpeg.res = 300,
  device.height = 5,
  device.width = 8,

  toplabelvar = NULL,
  ylim = NULL,
  divideby = NULL,
  ylabel = NULL,
  xlabel = NULL,
  mar = NULL,
  addlegend = FALSE,
  main = NULL,
  cex.main = 1,
  cex.label = 1,
  cex.names = 0.8,
  las.xnames = 0,
  las.ynames = 1,
  savedata = FALSE,
  outfolder = NULL,
  outfn = NULL,
  outfn.pre = NULL,
  outfn.date = TRUE,

  ...
)

Arguments

x	Data frame or comma-delimited file (*.csv) - a frequency table.
xvar	String. Name of X variable.
yvar	String. Name of the y variable (e.g., FREQ).
grpvar	String. Name of the variable for grouping.
errbars	Logical. If TRUE, error bars are added to bar plot (sevar or psevar must also be populated).
x.order	String or Vector. Define order of xvar based on y values: descending ("DESC") or ascending ("ASC") or vector of row numbers. If NULL, the order of the input table is used.
sevar	String. Name of the variable with standard error values.
psevar	String. Name of the variable with percent standard error.
device.type	String. Type(s) of device for plotting ("dev.new", "jpg", "pdf").
jpeg.res	Integer. Resolution for jpeg image.
device.height	Integer. Height (in inches) of barplot, if writing to file.
device.width	Integer. Width (in inches) of barplot, if writing to file.
horiz	Logical. If TRUE, bars are drawn horizontally with first bar at the bottom. If FALSE, bars are drawn vertically with first bar to the left (barplot parameter).
toplabelvar	String. Name of variable in x for adding labels to place above each bar (e.g., NBRPLOTS.gt0).
ylim	Number. A vector of min and max values, c(min,max) for the y axis (or x axis if horiz=TRUE). If NULL, defaults to maximum y value. If errbars=TRUE, the ylim defaults to the maximum y value plus the standard error.
divideby	String. Conversion number for output ('hundred', 'thousand', 'million').
ylabel	String. Label for the y axis (same as ylab).
xlabel	String. Label for the x axis (same as xlab).
mar	See par.. A numerical vector representing number of lines for margins (c(bottom, left, top, right).
addlegend	Logical. If TRUE, adds legend to bar plot (only applicable if grouping).
main	String. Title for plot.
cex.main	Number. Expansion factor for title.
cex.label	Number. A number representing cex in barplot (size expansion of x and/or ylabels.
cex.names	Number. Expansion factor for axis names (bar labels) (e.g., 0.5 represents half the size.
las.xnames	Number. The direction of x variable names (0,1,3). 0:diagonal (Default), 1:horizontal; 3:vertical.
las.ynames	Number. The direction of y variable names (0,1,3). 0:diagonal (Default), 1:horizontal; 3:vertical.
savedata	Logical. If TRUE, writes output data to outfolder (jpg and pdf).
outfolder	String. The name of the output folder. If savedata=TRUE, all output saved to the outfolder. If savedata=FALSE, only a text file of input parameters is saved.
outfn	String. The name of the output file if savedata=TRUE (*.csv). Do not include extension. If NULL, the file will be named BARPLOT_'yvar_date'.csv
outfn.pre	String. Add a prefix to output name (e.g., "01").
outfn.date	Logical. If TRUE, add date to end of outfile (e.g., outfn_'date'.csv).
overwrite	Logical. If TRUE and exportshp=TRUE, overwrite files in outfolder.
...	additional arguments to pass to barplot(), including a list of arguments for legend() arguments (e.g., args.legend=list(x="topleft", bty="n"), for moving legend to topleft and removing box around legend).

Details

If parameters = NULL, then it will prompt user for input.

Value

Outputs barplot to display window.

Note

If savedata = TRUE, writes a jpg and pdf of barplot to outfolder.

To add legend parameters, add a parameter named args.legend, defined as a list of specific legend parameters (see ?legend)... e.g., args.legend=list(x="topright"). If specifying x and y, x defines the lower right corner of legend box and y defines the upper right corner of box.

Examples

# Set up data frame for example
ftyptab <- data.frame(cbind(FORTYPCD = c(182, 184, 201, 221, 265),
                            FREQ = c(110, 7, 900, 410, 155),
                            SE = c(10, 11, 18, 14, 22)))
                            
# Create basic barplot                           
datBarplot(x = ftyptab, xvar = "FORTYPCD")
	
# Add standard errors to basic barplot
datBarplot(x = ftyptab, xvar = "FORTYPCD", errbars = TRUE, sevar = "SE")
