Hello Everyone,
I am using R for creating heatmap from a square matrix. Below is my script
to do so
my_map <- read.csv("Desktop/input.csv", sep=",")
my_matrix <- data.matrix(my_map)
my_heatmap <- heatmap(my_matrix, Rowv=NA, Colv=NA, col = cm.colors(256),
scale="column", margins=c(5,10))
I get a beautiful plot as output, but I could not save this plot as an
image. I would like it to be in either jpg/png/svg/bitmap/ or PDF format.
Can some one advice me how to write this output to file ?
I am using R 2.10.1 in Ubuntu 10.04
TIA
Chakri

Can anyone direct me to literature/tutorial that explains how to slant labels (at an angle) or how to reduce font size ? http://r.789695.n4.nabble.com/file/n3413871/heatmap.jpg -- View this message in context: http://r.789695.n4.nabble.com/How-to-save-heatmap-as-image-or-pdf-tp3412542p3413871.html Sent from the R help mailing list archive at Nabble.com.
