\usage{
ggheatmap(df, x=NULL, y=NULL, value=NULL, grouping="mean")
}
\arguments{
  \item{df}{A data frame in "long" format.}
  \item{x}{The variable that will be used for X axis in the heatmap. If not specified, the first column will be used.}
  \item{y}{The variable that will be used for Y axis in the heatmap. If not specified, the second column will be used.}
  \item{value}{The variable that will be used for colouring the heatmap. If not specified, the third column will be used.}
  \item{grouping}{The function that will be used to group if there is more than one observation for each X-Y combination. "mean" or "median" are posible, defaulting to "mean".}
