Dear Sir,
Please help me solving the error occurring during the execution of the code
given below.
library("openxlsx")
library(gplots)
library("RColorBrewer")
rix <- read.xlsx(file.choose(), sheet = 1, colNames = TRUE,rowNames = TRUE)
rawdata <- data.matrix(rix)
colors =
c(seq(-2,-0.5,length=100),seq(-0.5,1,length=100),seq(1,2,length=100))
my_palette <- colorRampPalette(c("green", "black", "red"))(n = 299)
heatmap.2(rawdata, col=my_palette, scale="row", key=TRUE, symkey=FALSE,
density.info="none", trace="none", cexRow=0.5, Rowv = FALSE, Colv=FALSE,
breaks=colors)
Error in seq.default(min.raw, max.raw, by = min(diff(breaks)/4)) : invalid
(to - from)/by in seq(.)
In addition: Warning messages:
1: In heatmap.2(rawdata, col = my_palette, scale = "row", key = TRUE, :
Using scale="row" or scale="column" when breaks arespecified can produce
unpredictable results.Please consider using only one or the other.
2: In heatmap.2(rawdata, col = my_palette, scale = "row", key = TRUE, :
Discrepancy: Rowv is FALSE, while dendrogram is `none'. Omitting row
dendogram.

Please find the data set attached with the email.
Thanking you.

Pijush
