list of lists to matrix
Please supply some sample data.
The easiest way to supply data is to use the dput() function. Example with your file named "testfile":
dput(testfile)
Then copy the output and paste into your email. For large data sets, you can just supply a representative sample. Usually,
dput(head(testfile, 100)) will be sufficient.
Simpe example:
aalist <- list(aa = c(3.0, 2.9, 2.7), bb = c(0.86, 0.76, 0.66),
cc= c(0.07, 0.04, 0.04), cc = c("a", "b", "c"))
dput(aalist)
The attached text file was useful but actual or example data is much better.
