描述----------Description----------

Provides a function to produce rudimentary ascii graphics directly in the terminal window.
提供了一个基本的ASCII图形的功能，直接在终端窗口中。

txtplot provides the basic plotting function of two numeric vectors. All other functions below are based on this.<br> txtcurve is a text based equivalent of the curve function<br> txtdensity is a text based density estimation function based on the density function<br> txtacf is a text based equivalent of the acf function and based on the acf function.<br> txtbarchart is a text based barplot and plots the relative frequences of the occurences of the different levels of a factor (in percent)
txtplot两个数值向量提供了基本的绘图功能。所有其他功能的基础上。<BR>txtcurve是一个基于文本的相当于curve功能<BR>txtdensity是一个基于文本的密度估计函数的基础上的density的功能<BR>“txtacf是acf功能相当于一个基于文本的和根据acf功能。<BR> txtbarchart是一个基于文本的barplot绘制的相对频率的频道出现的不同层次的因素（％）


用法----------Usage----------


txtplot(x, y = NULL, pch = "*", width = round(options()$width*0.8),
        height = round(0.25*width), xlab = NULL, ylab = NULL,
        xlim = NULL, ylim = NULL)

txtcurve(expr, from = NULL, to = NULL, n = 101,
         pch = "*", width = round(options()$width*0.8),
         height = round(0.25*width), xlab = NULL, ylab = NULL)

txtdensity(x, pch = "*", width = round(options()$width*0.8),
        height = round(0.25*width), xlab = NULL, ylab = NULL)

txtacf(x, pch = "*", lag.max = 20, type = c("correlation", "covariance", "partial"),
       na.action = na.fail, demean = TRUE, width = round(options()$width*0.8),
       height = round(0.25*width), xlab = NULL, ylab = NULL)

txtbarchart(x, pch = "*", width = round(options()$width*0.8),
            height = round(0.25*width), ylab = NULL)



参数----------Arguments----------

参数：x
numeric containing the x-values to plot (for txtbarchart this needs to be of class factor). NA, NaN are removed for plotting. Infinities cause an error  
数字包含的x值图（txtbarchart这需要的类因子）。 NA大，NaN被删除的图。无穷大造成的错误


参数：y
numeric containing the x-values to plot (needs to be of the same length as x). If NULL the numeric x is plotted against 1:length(x). NA, NaN are removed for plotting. Infinities cause an error  
数字含有的x值的积（需要具有相同的长度为x）。如果为NULL数字x暗算1:length(x)。 NA大，NaN被删除的图。无穷大造成的错误


参数：pch
Plotting symbol  
绘图符号


参数：width, height
Width and height of the plots in points  
以点的曲线的宽度和高度


参数：xlab, ylab
labels for x and y axis  
为x和y轴的标签


参数：xlim, ylim
limits for x and y axis in plot, if equal to NULL automatically determined from x and y.  
为x和y轴在图的限制，如果等于NULL自动确定从x和y。


参数：expr
An expression to plot (containing x)  
图（包含x）的表达式，


参数：from,to
Defines boundaries of plotting region for expr in txtcurve  
定义画图区域的边界expr的txtcurve


参数：n
integer specifying the number of x values between from and to  
整数，并从指定的x值之间


参数：lag.max, type, na.action, demean
arguments for call of acf function, see ?acf for details  
acf函数调用的参数，请参阅ACF的详细信息，


注意----------Note----------

Due to rounding to a relatively crude grid results can only be approximate! The equally spaced axis ticks, for example, may be non-equally spaced in the plot.
由于舍入到一个相对粗糙的网格结果只能是近似！等距轴刻度线，例如，可能是在图非等距隔开。

Due to the crude grid also there might be several points per pixel. The function uses the same plotting symbol no matter how many points coincide on one pixel
由于粗网格，也有可能是几个点，每个像素。该函数使用相同的绘图符号，不管多少点重合在一个像素点
