From NUM to INT
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.

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 ... $ Meti : int 352645997 334146268 767208656 171567266 462747405 414905627 237010514 387480048 214671355 328813226 ... $ Fungii : int 43645 19009 15998 2189 8972 8240 3133 17922 6156 13746 ... $ Protozoai: int 3220523 1851891 3252462 1665675 34123768 23175015 203685 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, -- Andre
