Calculating the median

I have following (exponential) values and want to calculate their median using R:

1.0584e+00
1.1618e+01
4.9097e+00
1.3595e+01
4.2209e+01
4.6901e-01
2.4911e+00
1.2441e+01
6.8128e+00
1.3581e+01
1.4373e+01
1.2828e+00
7.7811e+00

Here is what I am doing:

data <- read.table("path")
median(data[ ,1])

Due to values being in exponential, I am not getting the correct median. Alternatively, you may also suggest how can I change these values into normal floating point values.

Solution

  • What are you getting for the median. Seems to work for me. Maybe you have these as "factor"s and you need to convert with as.numeric(as.character())

    > median(vec)
[1] 7.7811
> vec
 [1]  1.05840 11.61800  4.90970 13.59500 42.20900  0.46901  2.49110 12.44100  6.81280 13.58100
[11] 14.37300  1.28280  7.78110
