I have two date objects X <- c("01-03-1993", "01-05-1997") #Mar 1993 and May 1997 Y <- c("01-02-1995", "01-08-1999") #Feb 1995 and Aug 1999 and a time series object A <- ts(rnorm(120), freq=12, start=c(1992,8)) #Aug 1992 to Aug 2002 I want to create a binary (0-1) vector B that is of length 1:(A). B should have value 1 for the time periods

Hello, If I have a character string like d <- c("1990m3", "1992m8") #March 1990 and Aug 1992 what is the easiest way to convert it into any standard 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

Hi, How can one ask getSymbols to obtain data within a specified time interval? For example, if I am downloading US PPI data: usppi <- as.zoo(getSymbols("PPIACO", src="FRED", verbose=TRUE, auto.assign=FALSE)) How do I ask getSymbols to truncate starting from Jan-1970 until present? I looked up the help file but couldn't find anything. Another newbie question, can I

Hi, I have been running the ccf() function to find cross-correlations of time series across various lags. When I give the option of plot=TRUE, I get a plot that gives me 95% confidence interval cut-offs (based on sample covariances) for my cross-correlations at each lag. This gives me a sense of whether my cross-correlations are statistically significant or not. However, I am unable to get R to

Hi, I have a simple linear regression for which I want to obtain HAC corrected standard errors, since I have significant serial/auto correlation in my residuals, and also potential heteroskedasticity. Would anyone be able to direct me to the function that implements this in R? It's a basic question and I'm sure I'm missing something obvious here. I looked up this post:

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.

Hi, I have an vector object that looks like DA <- c("1991q1", "1993q2") (first quarter of 1991 etc) and I want to convert it into a date object using as.Date(). I did this for montly data but am stumped when it comes to dealing with quarterly data and as.Date. Would anyone be able to help? Would be very grateful for any advice, sorry for being such an R-newbie!

Referring to the log messages from my previous mail… I confused myself (and probably others) by reading the “Adding MemMgr 0x55555959f440“ message as “Registering MemMgr 0x55555959f440”. Thus the address mismatch made no sense. How could we be registering a `MemMgr` address/key that does not match once we arrive in `notifyObjectLoaded` method? Answer: Because the registrations is NOT coming

Hi r-users,   I would like to overlap a smooth line on the histogram.  I tried using spline but it does not work. sq     <- seq(0,900,by=50) sq.50  <- as.character(sq) datobs <- sum_pos ## first, plot histogram histo <- hist(datobs,breaks=sq,freq=F) ## extract counts from histogram and calculate the probability in ## each specified interval. Also check the length of the interval is

Hi, I would like to plot a histogram with the following codes, and I would like to make the tick intervals smaller. I tried to add "lab=c(1,1,12)", but nothing changes. par(mfrow=c(1,1),font=1, cex=0.8) hist (data1, seq(-0.01,0.3,0.01),freq = FALSE, main="Figure1.",xlab="return",lab=c(1,1,12)) lines(density(data1), col="blue") Could anyone give me sone

Buenos días: Después de más de 20 años en SAS, ahora igual me toca trabajar en R. Y la transición es muy dura: la "lógica" de los dos lenguajes es, para mi, totalmente diferente. Disculpen si lo que pregunto es una obviedad, pero llevo todo el día con esto y no logro encontrar la respuesta adecuada con google. Estoy intentado crear una función que realice una descriptiva simple de

This code gives an error: a <- ts(1:10, start=0, freq=10) b <- ts(1:10, start=1, freq=10) ts.intersect(a,b) This one works normally (and correctly): a <- ts(1:10, start=0) b <- ts(1:10, start=1) ts.intersect(a,b) Antonio, Fabio Di Narzo.

Hi All, Here is something that sounds simple, but I'm having trouble getting it. I have a data frame with two columns, the first is date and the second is employee ID. I'd like to plot date on the horizontal axis, employee ID on the vertical axis, and the number of times the employee appears for the given date as a color. I've kluged something where I make a table (table(date, id))
