order.group {agricolae} R Documentation

## Ordering the treatments according to the multiple comparison

### Description

This function allows us to compare the treatments averages or the adding of their ranges with the minimal significant difference which can vary from one comparison to another one.

### Usage

order.group(trt, means, N, MSerror, Tprob, std.err, parameter=1, snk=0,
DFerror=NULL,alpha=NULL,sdtdif=NULL,vartau=NULL,console)


### Arguments

 trt Treatments means Means of treatment N Replications MSerror Mean square error Tprob minimum value for the comparison std.err standard error parameter Constante 1 (Sd), 0.5 (Sx) snk Constante = 1 (Student Newman Keuls) DFerror Degrees of freedom of the experimental error alpha Level of risk for the test sdtdif standard deviation of difference in BIB vartau matrix var-cov in PBIB console logical, print output

### Details

This function was changed by orderPvalue function that use agricolae. Now the grouping in agricolae is with the probability of the treatments differences and alpha level.

### Value

The output is data frame.

 trt Treatment Levels, Factor means height, Numeric M groups levels, Factor N replications, Numeric std.err Standard error, Numeric

### Note

It is considered 81 labels as maximum for the formation of groups, greater number will not have label.

library(agricolae)
treatments <- c("A","B","C","D","E","F")
means<-c(20,40,35,72,49,58)
std.err<-c(1.2, 2, 1.5, 2.4, 1, 3.1)
replications <- c(4,4,3,4,3,3)
MSerror <- 55.8
value.t <- 2.1314
groups<-order.group(treatments,means,replications,MSerror,value.t,std.err,console=FALSE)
print(groups)
