+# Lattice Design
+
+```{r, include=FALSE, echo=FALSE}
+source(here::here("settings.r"))
+```
+
+## Background
+
+Yates (1936) proposed this method of arranging agricultural variety trials involving a large number of crop varieties. These types of arrangements were named a quasi-factorial or lattice designs. His paper contained numerical examples based on the results of a uniformity trial on orange trees. A special feature of lattice designs is that the number of treatments, t, is related to the block size, k, in one of three forms: t = k^2^, t = k^3^, or t = k(k +1).
+
+Even though the number of possible treatments is limited, a lattice design may be an ideal design for field experiments with a large number of treatments.
+
+Statistical model for lattice design:
+
+$Y_{ijk} = \mu + \alpha_i + \gamma_j + \tau_t + \beta_k + \epsilon_ijk$
+
+where, $\mu$ is the experiment mean, š½ is the row effect, š¾ is the column effect, and š is the treatment effect.
+
+## Example Analysis
+
+The data used in this example is from a balanced lattice experiment in cotton containing 16 treatments in a 4x4 layout in each of 5 replicates. The response variable in this data is the precentage of young flower buds attacked by boll weevils.
+
+Let's start the analysis firstly by loading the required libraries:
+
+::: panel-tabset
+### lme4
+
+```{r, message=FALSE, warning=FALSE}

+Import data from agridat package. The data contains . This is a balanced experiment design
+```{r}

+ main="cochran.lattice")
+
+```
+
+```{r}
+data(burgueno.rowcol)
+dat <- burgueno.rowcol
+head(dat)

+Here, we can use the `desplot()` function from the 'desplot' package to visualize the plot plan from lattice design.
