[R] problem with data frame to numeric transformation

[Rui Barradas]

Hello,

You need to tell read.table that the table has headers.


# needed 'header=TRUE'
first <- read.table("RESIDSNEWr.csv", sep=";", quote="\"",
header=TRUE)[c(1)]
second <- read.table("RESIDSNEWr.csv", sep=";", quote="\"",
header=TRUE)[c(2)]
# see what they look like
str(first)
str(second)

is.numeric(first) ## FALSE
is.numeric(second) ## FALSE

is.numeric(first$aaa) ## TRUE
is.numeric(second$bbb) ## TRUE
# general purpose
sapply(first, is.numeric)
sapply(second, is.numeric)


And the rest works at the first try.

> calibKendallsTau(cc,cor(first,second,method="kendall"))
         bbb
aaa 4.420256
> 
> ## goodness-of-fit tests
> gf.cc <- gofCopula(cc,u,method="itau")
Progress will be displayed every 100 iterations.
Iteration 100 
[...etc...]
Iteration 1000 
> 
> gf.cc$pvalue
[1] 0.0004995005


Hope this helps,

Rui Barradas
