[R] HELP me please with import of csv to R

[William Dunlap]

You or nabble left out my suggestion to use dec="," in your
call to read.table (or read.csv, etc.)

  Did you use read.table(filename, ..., dec=",") when importing
  the data (so "30,3" is read as the number 30 and 3 tenths instead
  of as the character string "30,3")?

along with an example of what it did:

  > good <- read.table(header=TRUE, dec=",", text="x y\n1,1 2,1\n1 2\n")
  > str(good)
  'data.frame':   2 obs. of  2 variables:
   $ x: num  1.1 1
   $ y: num  2.1 2
