x |
The object. |

Unused. |
percent |
A numeric vector of percentages. |
hc |
A numeric vector of percentages. |
ci |
A flag specifying whether to estimate confidence intervals (by parametric bootstrapping). |
level |
A number between 0 and 1 of the confidence level. |
nboot |
A count of the number of bootstrap samples to use to estimate the se and confidence limits. |
parallel |
A string specifying the type of parallel operation to be used ('no', 'snow' or 'multicore'). |
ncpus |
A count of the number of parallel processes to use. |
average |
A flag specifying whether to model average the estimates. |
ic |
A string specifying which information-theoretic criterion ('aic', 'aicc' or 'bic') to use for model averaging . |
A data frame of the percent and concentrations.
