From NUM to INT

So, How could I implement this, Bert?

I really need that the variable be converted unto an integer, and it seems
that my numbers are much higher than that threshold you stated.

Thanks,

Andre

No.

From ?as.integer:

"Note that current implementations of R use 32-bit integers for
integer vectors, so the range of representable integers is restricted
to about +/-2*10^9: doubles can hold much larger integers exactly. "

Cheers,

Dear all:

I converted the columns (Baci, Meti, Fungii, Protozoai) into integers
(using excel) and then imported the data (.txt) into R. Interestingly,
the
other three variables were loaded as INT, but the 'Baci' one continued
as
Num.

I imported the data using the following command line:

X <- read.delim(file.choose(),
                 header = TRUE,
                 dec = ".")

Here is the structure of X:

str(X)

'data.frame': 115 obs. of  5 variables:
 $ ID       : Factor w/ 61 levels "107ZRED","112BLKW",..: 8 12 15 18 26
27
29 31 32 36 ...
 $ Baci     : num  2.90e+12 5.55e+11 9.46e+11 8.13e+11 4.06e+11 ...

4261780 43110492 69802572 ...


I need Baci as an integer, and tried to convert it using as.integer
function, but was not successful.


Could anyone please help me to solve this problem.

Thanks,
