Dear Regiane

The easiest way I found to transfer data from Excel to 
data.frames in R was to use copy and paste function.

Let’s say you have a 4 column x 101 row data set in Excel 
(columns A to D; row 1 with titles: Species, Sex, Weight and 
Length, rows 2 to 101 with data).

In Excel make a new column (column E) and in cell E2 write 
=A2&" "&B2&" "&C2&" "&D2. Fill all lines (2 to 101) of column 
E with this formula. Copy cells E2 to E101.

In R write:
data.dat <- data.frame(scan(what = list (Sp=" ", Sex=" ", 
Wt=0, Lt=0), sep=" "))

*** use dec=","  if your system uses comma (,) as decimal 
separator: ... sep=" ", dec=","))
Also note that in this example Sp and Sex are factors.

When "1:" appears in R press Ctrl+v

Good luck,

Antonio Olinto
