Plotting

[crabbitt42]

I tried doing a contour plot with the data in the attached csv file (columns are "x", "y", and "z"; row names are also included). I figured this would be easy enough with "filled.contour()" or "ggplot()", but neither seems to like my input data. I can create a scatter of x vs y easily enough, but z doesn't seem to be working for me. Any idea what the problem is?

Oh, and in spite of the name of the file, I have tried converting it to a data frame, but that doesn't seem to solve my problem.

I think it has to do with the data not being enough or that the data is irregularly spaced (see this link for more discussion).

Try:

library(ggplot2)
library(dplyr)
read.csv('matrix.txt') %>% 
    tbl_df() %>% 
    ggplot(aes(x, y, z = z)) +
    stat_density2d() +
    theme_bw()
