Thank you Ray and Jim.
It works with file.choose().
I post following the output.

Hi,
I have the file DATOS1 in the directory E:/R 3.0.2/R-3.0.2/bin/x64.
If I try to load it, R returns me this error:
getwd()
[1] E:/R 3.0.2/R-3.0.2/bin/x64
DATOS1-matrix(scan(E:/R 3.0.2/R-3.0.2/bin/x64/DATOS1),ncol=8)
Error en file(file, r) : no se puede abrir la conexión
Además: Mensajes de aviso perdidos
In file(file, r) :
no fue posible abrir el archivo 'E:/R 3.0.2/R-3.0.2/bin/x64/DATOS1':
No such file or directory
The file DATOS1 is a Text Document with this composition:
32 17 67 112 28 10 17 71
329 64 142 32 140 66
22 25 66 122 23 12 25 68
18 25 60 101 21 14 12 66
210 67 125 20 152 67
417 65 126 37 14 25 68
218 64 123 24 120 71
207 63 109 20 10 34 69
226 62 123 27 127 73

310 65 125 31 160 72
227 62 113 23 14 25 78
If it's a text document created with a Windows application, then it is very
likely that the file name is really DATOS1.txt. Another useful thing to do in
Windows is to use file.choose() whenever you want to open a file:
DATOS1 - matrix(scan(file.choose()), ncol = 8)
The unit E: is an external hard disk.
It seems like the path were wrong.
I´ve read the FAQ´s, the Windows FAQ´s, the R document about scan() function
and the related sections of An Introduction to R and the Import/Export
manual, but I can´t find any answer of this error.
Can anybody help me, please?
Thank you
Hope this helps,
Ray Brownrigg
