You did not succeed in creating a plot that the rhelp mail server would accept.
My guess is that the first column is a factor variable and that you did not use
colClasses when doing your data input.
dd <- read.table(text="2005-01-04 -2.76105935648091
2005-01-19 -9.60813496025994
2005-01-22 -7.92101965866777
2005-02-19 -1.61308152604905
2005-02-24 -1.51497015807712
2005-05-09 -2.06465797304654

2005-12-15 -1.08933890547705", colClasses=c("Date","numeric")
)
No problems with:
plot(dd[[1]], dd[[2]], xlim=c(as.Date("2005-01-01"),as.Date("2005-12-31")))
