...rd date form; for example, d <- c("01/03/1990", "01/08/1992") I looked at as.Date but it doesn't seem to address my problem as I have an "m" stuck in the middle of my character string which R does not recognise. Would be very grateful for any help on this.

...f a value lies between 2 other values. For example, A <- ts(rnorm(120), freq=12, start=c(1992,8)) X <- 0.5 Y <- 0.8 I would like to create a new vector C for which C[i] is 0 if A[i] lies in between X and Y. Would be grateful for any help.

...cross-correlations are statistically significant or not. However, I am unable to get R to return the value of these critical values to me in say, an object or vector form. Would anyone be able to help me extract the critical values (at 95%) from the ccf() function?

...? I looked up the help file but couldn't find anything. Another newbie question, can I specify the frequency of the data I want from FRED? The USPPI data above gives me monthly data, is there a way I can ask to obtain annual data? Thanks very much, I'd be grateful for any help on this.

...se the coeftest() function in package lmtest, but when I tried to assign an object: result <- coeftest(regre, NeweyWest), where regre is an object of class lm, this returned an error. I'd be grateful for any advice, since I'm sure I'm making one of those simple bloopers. Thanks!

...lso between May-97 and Aug-99, but zero otherwise. Would anyone have any ideas on how to do this? I would paste the code I am trying, but it would confuse rather than clarify (R newbie!). Am getting really lost in 'for' and 'if' loops, so would really appreciate any help! Thanks!

Hi, Would anyone know if it is possible to run a Beveridge Nelson decomposition of a univariate time series object in R? I searched in the help files but didn't come across any potential methods.
