The package is used for statistical analysis of Plant Breeding experiments.

Package Website https://nandp1.github.io/gpbStat/

Note: In the latest version 0.3.1 estimation of Kings Variance is not included.

## Installation

Install latest package from Github  through
``` r
install.packages("devtools")
library(devtools)
install_github("nandp1/gpbStat")
```

Install gpbStat from [CRAN](https://CRAN.R-project.org) with:

``` r
install.packages("gpbStat")
```

## Example

Line by Tester analysis (only crosses).

```{r example}

# Loading the gpbStat package
library(gpbStat)

# Loading dataset
data(rcbdltc)


## Now by using function ltc we analyze the data.
## The first parameter of `ltc`  function is "data" followed by replication, line, tester and dependent variable(yield)
results1 = ltc(rcbdltc, replication, line, tester, yield)

## Viewing the results
results1
```

```{r}
# Similarly we analyze the line tester data containing only crosses laid out in Alpha lattice design.
# Load the package
library(gpbStat)

# Loading dataset
data("alphaltc")

# Viewing the Structure of dataset
str(alphaltc)
# There are five columns replication, block, line, tester and yield.


## Now by using function ltc we analyze the data.
## The first parameter of `ltc`  function is "data" followed by replication, line, tester, dependent variable(yield) and block.
## Note: The "block" parameter comes at the end.
results2 = ltc(alphaltc, replication, line, tester, yield, block)

## Viewing the results
results2
```


```{r}
# Line x Tester analysis for multiple traits laid in Alpha lattice design.
# Load the package
library(gpbStat)

#Load the dataset
data("alphaltcmt")

# View the structure of dataframe.
str(alphaltcmt)

# Conduct Line x Tester analysis
result3 = ltcmt(alphaltcmt, replication, line, tester, alphaltcmt[,5:7], block)

# View the output
result3
```
