I get the following error:
Error in row.names<-.data.frame(*tmp*, value = value) :
invalid 'row.names' length
Here is my script
library("RColorBrewer")
library("picante")
library("vegan")
library("ggplot2")
# read OTU data file for BB cultures
read.csv(file = "Heatmap_BB.csv", row.names = 1, header=TRUE, sep=",") -> BB
##creating the data tables for the heatmap.
BBnames <- BB[2:3] #here I assing the lables to be used later in one vector
hmBB <- BB[, 4:ncol(BB)]
hmBBmatrix <- (BB[,4:ncol(BB)])
hmBBmatrix
rownames(hmBBmatrix) <- BBnames
Can anyone help?
