Greetings R users,

I have a curious problem.  I read in a csv file (subset shown below) as
normal
data=read.table("C:/Users/Chaz/Desktop/test.csv",sep=",",header=TRUE,
na.strings=".")

However, the numbers from the dataset are not registered as numeric:

is.numeric(data$Mesh)
[1] FALSE

When I try as.numeric, it converts all the values to different integers.
This changes the analysis as I would like calculate simple things such as
the means and standard deviation.  Any thoughts would be appreciated.


 Mesh SubQ Edge  90 10 55  60 25 45  60 12 85  50 50 90  45 80 70  40 45 45
80 40 65  100 65 58
