Hello all: Any ideas on how can I set the X axis
limits to week 1? I tried the
but I get an error message. It works for the Y axis

df <- data.frame(date = seq(Sys.Date(), len=100, by="1
day")[sample(100, 50)],price = runif(50))
df <- df[order(df$date), ]
dt <- qplot(date, price, data=df, geom="line")
dt$aspect.ratio <- 1/4
dt + scale_x_date()
 dt + scale_x_date(format="%m/%d")
 dt + scale_x_date(format="%W")+
scale_y_continuous(limits = c(0, NA))
