Hi Jean,
Problem result: the 1st column value must be complete for heatmap to run correctly. This solved the same problem I had with vegdist. Thank you for your help.

The error appears to be a result of the missing values yielded by the dist() function on your matrix. See https://stat.ethz.ch/pipermail/r-help/2009-July/204443.html.

The first column is a numeric row name, it mustn't take part of the heatmap. I change it to text and try with and without "row.names=1" Both give me error.

SPIV2 <- read.csv("C:/Temp/SPI V2.csv") heatmap(as.matrix(SPIV2), na.rm=TRUE) Perhaps you modified SPIV2 in some way prior to running heatmap()?
