Hi there I have some timeseries data which I plot in a OHLC Plot. In the same plot I'd like to have the EMA of this timeseries. I tried to add the EMA point to OHLC with lines(), but this doesn't work. Has anyone an idea how to handle it? Regards, Michael Zak

...fine when run from the command line. But when run inside a function, only the last one run is visible. Here's an example. test.addTA <- function(from = "2010-06-01") { getSymbols("^GSPC", from = from) GSPC.close <- GSPC[,"GSPC.Close"] GSPC.EMA.3 <- EMA(GSPC.close, n=3, ratio=NULL) GSPC.EMA.10 <- EMA(GSPC.close, n=10, ratio=NULL) chartSeries(GSPC.close, theme=chartTheme('white'), up.col="black", dn.col="black") addTA(GSPC.EMA.3, on = 1, col = "#0000ff") addTA(GSPC.EMA.10, o...

Can somebody help me in finding package/Example in R which could do EMA(Exponential Mean Average). I installed "TTR" package but the 'EMA" function which I was trying to use is giving the following error. Error: Could not find function "EMA" Thanks & Regards, Thomas [[alternative HTML version deleted]]

Hi, I'm currently using EMA package to make clustering and heatmaps. The online doc concerning the package gives the following example code: data(marty) c<-clustering(marty, metric="pearson", method="ward") clustering.plot(c, title="Hierarchical Clustering\nPearson-Ward") which is working pe...

Hi, Just wondering for the SMA and EMA in package TTR, is it possible to me to code it so that, say if I need to calculate SMA (x, n=100), when the sample size is less than 100, it will give me the SMA (x, k) where k is the sample size of the data? Right now it only gives me an invalid n error. Thanks! [[alternative HTML version dele...

Hi Does anyone know of any R routines to send emails from R, under Windows? I thought about writing such a facility using the R(D)COM package to drive e.g. MS Outlook, but I don't want to reinvent the wheel. I have found a function Sys.mail in the library syskern, but this only works under Unix by shelling out a mail command. Thanks, David

...which makes the game wait in some sort of I/O which them implies both the CPU and GPU speed get reduced because the process spends a lot of time doing...nothing... just wait for that something. How would you recommend to find such bottleneck? Do you reckon is possible? Thanks in advance, Cheers, Ema! :-)
