factor1 |
Numeric or complex vector containing the factor 1 levels. |
factor2 |
Numeric or complex vector containing the factor 2 levels. |
repet |
Numeric or complex vector containing the replications. |
resp |
Numeric or complex vector containing the response variable. |
respAd |
Numeric or complex vector containing the additional treatment. |
quali |
Logic. If TRUE (default), the treatments are assumed qualitative, if FALSE, quantitatives. |
mcomp |
Allows choosing the multiple comparison test; the default is the test of Tukey, however, the options are: the LSD test ('lsd'), the LSD test with Bonferroni protection ('lsdb'), the test of Duncan ('duncan'), the test of Student-Newman-Keuls ('snk'), the test of Scott-Knott ('sk'), the Calinski and Corsten test ('ccF') and bootstrap multiple comparison's test ('ccboot'). |
fac.names |
Allows labeling the factors 1 and 2. |
sigT |
The signficance to be used for the multiple comparison test; the default is 5%. |
sigF |
The signficance to be used for the F test of ANOVA; the default is 5%. |
unfold |
Says what must be done after the ANOVA. If NULL (default), recommended tests are performed; if '0', just ANOVA is performed; if '1', the simple effects are tested; if '2', the double interaction is unfolded. |
The arguments sigT and mcomp will be used only when the treatment are qualitative.
The output contains the ANOVA of the referred CRD, the Shapiro-Wilk normality test for the residuals of the model, the fitted regression models (when the treatments are quantitative) and/or the multiple comparison tests (when the treatments are qualitative).
The graphics
can be used to construct
regression plots and plotres
for residuals
plots.
