Data values |
distribution |

main |
Chart Title |
sub |
Chart Subtitle |
groupsize |
Group size for grouped data. Data must be sorted by groups. Currently only a groupsize of 1 is supported. |
mrlength |
Number of observations used in the moving range to compute the within standard deviation for groupsize = 1. |
alpha |
Probability of a Type I error. |
tol |
Sigma multiplier for capabilities statistics. Usually defined as 5.15 or 6. |
unbias_sub |
Logical value as to whether the subgroup standard deviation should include the unbiasing constant. Default is TRUE. |
unbias_overall |
Logical value as to whether the overall standard deviation should include the unbiasing constant. Default is FALSE. |
density |
Logical value to control the display of the density curve. Default is FALSE. |
binwidth |
Overrides automatic determination of bin width in histogram. If set to -1 (default) then the function automatically calculates the optimum binwidth. |
plot |
Logical value to control plotting. Default is TRUE |
