Just convert qw to a factor:
require(RODBC)
channel <- odbcConnectExcel("f:/teste.xls")
data <- sqlFetch(channel, "Sheet1")
data$qw <- factor(data$qw)
> Tha factors variables have tha values enconde this form
> (1=Yes,2=No and 9 = NA
If you want to use those levels, you could use
data$qw <- factor(data$qw, levels=c('Yes', 'No', 'NA'))
