Extra labels for Heatmap

[bhive01]

I work with field data where blocks effectively represent data, but in many cases the Row and Column isn't terribly helpful since these are little more than coordinates (1, 3). I hacked the functions to allow adding an extra label that is input as a matrix or data.frame or similar, of the same dimensions as the data.

## un-comment to install my version
#devtools::install_github("bhive01/d3heatmap")

require(d3heatmap)

#create fake data
df1 <- data.frame(matrix(runif(300), 30, 10))

#create fake, but unique labels
df2 <- NA
for (i in 1:300) {
    df2[i] <- paste0(sample(LETTERS, size=5), collapse="")
    }

df2 <- data.frame(matrix(df2, 30, 10))

#plot without dendrogram or scaling
d3hmplot <- function(data, labels = NULL) {
    d3heatmap(data, labels , Rowv = FALSE, Colv = FALSE, dendrogram = "none", scale="none", distfun = NULL)
}

#without extra labels
d3hmplot(data=df1)

#with extra labels
d3hmplot(data=df1, labels = df2)

I have not tested this with the dendrogram or scaling. It probably breaks when you do that, and labeling wouldn't make much sense then anyway.

Hey there, I'm planning to merge https://github.com/talgalili/d3heatmap/pull/86 into the package.

Could you verify if your PR adds to it or not?

Thanks!

(sorry for responding 4 years later :D I just took over maintaining the package)
