xĪdditional arguments to be passed to the generic function. xlim, ylimĪ numeric vector specifying the limits for the x-axis and the y-axis. xlab, ylabĪ string giving the label for the x-axis and the y-axis. titleĪ character string specifying the main title. label.limitsĪ character vector specifying the labels for control limits. label.centerĪ character specifying the label for center line. fillĪ logical value specifying if the in-control area should be filled with the color specified in qcc.options('zones')$fill. chart.allĪ logical value indicating whether both statistics for data and for newdata (if given) should be plotted. add.statsĪ logical value indicating whether statistics and other information should be printed at the bottom of the chart. If provided it is used for x-axis so it must be of the same length as the statistic charted. xtimeĪ vector of date-time values as returned by Sys.time and Sys.Date. See qccRules for possible values and their meaning. rulesĪ value or a vector of values specifying the rules to apply to the chart. confidence.levelĪ numeric value between 0 and 1 specifying the confidence level of the computed probability limits. It is ignored when the confidence.level argument is provided. nsigmasĪ numeric value specifying the number of sigmas to use for computing control limits. newsizesĪ vector as for the sizes argument providing further data sizes to plot but not included in the computations. newdataĪ data frame, matrix or vector, as for the data argument, providing further data to plot but not included in the computations. limitsĪ two-values vector specifying control limits. Several methods are available for estimating the standard deviation in case of a continuous process variable see sd.xbar, sd.xbar.one, sd.R, sd.S. std.devĪ value or an available method specifying the within-group standard deviation(s) of the process. centerĪ value specifying the center of group statistics or the ''target'' value of the process. For 'p', 'np' and 'u' charts the argument sizes is required.

For continuous data provided as data frame or matrix the sample sizes are obtained counting the non- NA elements of each row. sizesĪ value or a vector of values specifying the sample sizes associated with each group. This requires the definition of 'stats.newchart', 'sd.newchart', and 'limits.newchart'. One-at-time data of a continuous process variableįurthermore, a user specified type of chart, say 'newchart', can be provided. Standard deviations of a continuous variable typeĪ character string specifying the group statistics to compute. Value of a vector, refers to a sample or ''rationale group''. Each row of a data frame or a matrix, and each A data frame, a matrix or a vector containing observed data for
