I could use some advice regarding xyplot. I've got 2 time series. Both cover approximately the same period of time (ie, 1940 to 2009). But one series has annual data and the other has monthly data. One refers to university enrollment; the other to unemployment rates. Both are currently in the same data frame. I'd like to use the monthly times series as a light grayscale background for a plot of the annual time series, showing both series as type &quot...

Dear Sir/Madam, How to use getSymbols() to get annual data? For example, I need the annual stock price of APPLE from the year 2000 to 2016. How to write the command? I only know how to get the daily data. It is: getSymbols("AAPL",from="2000-01-01",to="2016-12-31") Thank you very much. Have a good week! Best regard...

Hi, I'd like to make a time series at an annual frequency. > a<-xts(x=c(2,4,5), order.by=c("1991","1992","1993")) Error in xts(x = c(2, 4, 5), order.by = c("1991", "1992", "1993")) : order.by requires an appropriate time-based object > a<-xts(x=c(2,4,5), order.by=1991:199...

Hello, I'm very new to R, and so my question is simple. I have data record with 80 years of daily temperatures in one long string. The dates are also recorded, in YYMMDD format. I'd like to learn an elegant simple way to pull out the annual averages. (Obviously, every 4th year has 366 days.) I know I can set up a formal loop to create annual records and then average. But R seems to have such neat methods, is there some better way to do this? Lucia [[alternative HTML version deleted]]

I have a monthly price index series x, the related return series y = diff(log(x)) and a POSIXlt date-time variable dp. I would like to apply annual blocks to compute for example annual block maxima and mean of y. When studying the POSIX classes, in the first stage of the learning curve, I computed the maximum drawdown of x: > mdd <- maxdrawdown(x) > max.dd <- mdd$maxdrawdown > from <- as.character(dp[mdd$from]) > to <...

...language), please see www.hydrology.uni-kiel.de/~schorsch/statistik/statistik_datenauswertung.pdf (pages 40-52) The dataset is: www.hydrology.uni-kiel.de/~schorsch/statistik/erle_stat.csv It contains a 10 year dataset. So far for introduction, now comes the problem: we often need cumulative *annual* sums (sunshine, precipitation), i.e. the sum must reset to 0 at the beginning of the year. I know of cumsum(), but I do not now how to split the dataset automagically into annual pieces so I can cumsum() every year separately. I have the strong hope that the solution is one of these one-liners w...

...than Shackles <nshackles@constellagroup.com>, ported from SAS code written by Renee Jaramillo <rjaramillo@constellagroup.com> Description: The RAGG package performs aggregation of gridded CMAQ model data. The pacakge reads event data from Models3 IO-API files and outputs the aggregated annual data in Models3 IO-API file(s). Aggegation came about as a means to provide CMAQ-based estimates of total annual deposition and average annual concentrations. CMAQ is an episodic model requiring detailed meteorological and emissions inputs. Because of the extensive inputs and the time required to...

hi everyone! hope you can help me here. i am a new R user. what i am trying to do is to find the maximum annual discharge from a daily record. i have a data.frame which includes date and the discharge. somewhat like this.. 10/1/1989 2410 10/2/1989 2460 10/3/1989 2890 ... ... ... 12/31/2005 5730 i have been browsing through the archives and fount out about the aggregate function and th...

I can also use the function to create monthly or segments or one big annual segment. Here is a function that I developed: groupingStrings<-function(yrs, numSplits) { unlist(lapply(yrs, function(x){ paste(x,formatC(numSplits, width = 2, flag = 0), collapse = "|", sep = "")})) } Here is an example of running the function: groupingStrings(2004:2006,...

Hi, I was wondering if there is a package I can use to convert my 22 annual observations to quarterly time series so that I will have 88 observations. Also, will there be any harm in doing so? will I loose any important data specific info? I want to run VARs in levels using TY method. Due to small sample, i will probably use a bootstrap method. Thanks! [[alternative...

Hello, I'm trying currently using barplot to summarize precipitation data. So far I've compiled total annual snow and rain accumulation in a table (attached). I've been successful at plotting it using the following code: fig=barplot(t(Annual_Precip_table), horiz=TRUE, space=0, col=c("grey70", "white"), axes=FALSE) . . The result is a stacked barplot with total annual rain represe...

I''m guessing this can only be done with javascript or can it be done with just Ruby ?

...sing funadable.org to purchase a yearly membership as a group. A year long membership at browsercam.com costs $480.00. This gives us 25 user accounts. I am proposing that 25 people throw in $19.20 for their 1/25th share of the membership cost. Once I have raised $479.40 I will purchase the annual membership and setup an account for all the participants. Keep in mind that the daily price for one user is $19.95, which is more than what you will need to pay for a year under this plan.

...nybody please help me understand AIC and BIC and especially why do they make sense? Furthermore, I am trying to devise a new metric related to the model selection in the financial asset management industry. As you know the industry uses Sharpe Ratio as the main performance benchmark, which is the annualized mean of returns divided by the annualized standard deviation of returns. In model selection, we would like to choose a model that yields the highest Sharpe Ratio. However, the more parameters you use, the higher Sharpe Ratio you might potentially get, and the higher risk that your model is o...
