Hello,
I must start by saying that I am an R novice and am sorry if this is a
no-brainer...
I have an csv file that contains a grid of 300x300 data points. Each point
represents
a 1Km square on a map. Each point is either a floating point number or NA. I
load the
data in with:
data <- read.csv("matrix.csv", sep=',')
Convert the data to a matrix with:
data_matrix <- data.matrix(data)
and then produce the heatmap with:
data_heatmap <- heatmap(data_matrix,Rowv=NA,Colv='Rowv',margin=c(0,0))
The heatmap is displayed in a separate window as expected and looks correct
apart
from fine white banding lines spaced out evenly over the image running
horizontally
across the image?
At first I thought it was my data but I checked that and its not. If I resize
the
image I then see white vertical lines and different horizontal lines appear?
I've tried a number of different settings but can't seem to get rid of these
lines.
If I can get rid of them the image will be ideal and just what I want. Does
anyone
have any idea of what I'm doing wrong?
Best regards,
Col.
