Dear R-helpers, In the following example I compute ret and returns the SAME way. In ret I use compute returns for EACH column and in returns I do it for the whole data frame. Could someone please tell me why I see a lagged result,by which I mean ret and returns are different by one lag. getSymbols("GOOG",src="yahoo") ret<-apply(GOOG,2,function(x) diff(log(x)) / lag(x,1) )

I have a data.frame named "df". The dput of df is at the bottom of this e-mail. What I'd like to do is replace the "n/a " values with NA. On Mac OSX, it works to do this: df[df == "n/a"] <- NA However, it does not work on Ubuntu. See below. Thanks in advance, Garrett > x <- df[27, 4] # complete data.frame dput is below > dput(x) "n/a?"

Hi group, I am trying to convert the organization of a data frame so I can do some correlations between stocks, I have something like this: stock.returns <- data.frame(rbind(c("MSFT","20110301",0.05),c("MSFT","20110302",0.01),c("GOOG","20110301",-0.01),c("GOOG","20110302",0.04))) colnames(stock.returns) <-

Hi all I have installed quantmod package but when I try to obtain GOOG data appers this message: Can anyone inform why itappears? I type getSymbols("GOOG",src="google") Thanks and Best Regards for all Error en download.file(paste(google.URL, "q=", Symbols.name, "&startdate=", : no fue posible abrir la URL '

Hey guys, i want to calculate the continuasly compounded returns for stock prices. Formula for CCR: R_t = ln(P_t/P_{t-1})*100 With R: First i have to modify the vectors, so that they have the same length and we start at the second observation. log(GOOG1[-1]/GOOG1[1:length(GOOG1)-1])*100 That does work with normal vectors. My Questions: 1) I want to use this for stock prices. so i

Hi All! I am interested in testing whether the means for the data I am investigating are equal to a specific value - let's say 0.01. I have already run a one-way ANOVA and know that the differences in the means are not significant, so now I want to know what values the means take on. "otestme" is the data I am working with (it would be hard for me to get into a form that would be

Just an attempt to avoid overflows with an explicit check, I don't know if there's a better way to identify corrupt input here.

From: David Riley <davidriley at chromium.org> virtio_gpu_get_caps_ioctl could return success with invalid data if a second caller to the function occurred after the entry was created in virtio_gpu_cmd_get_capset but prior to the virtio_gpu_cmd_capset_cb callback being called. This could leak contents of memory as well since the caps_cache allocation is done without zeroing.

Hi, I can't seem to figure out how to tell R to stop expanding an object. I would like to use the literal name rather than the expanded value. The issue occurs in a function I've been writing. The problematic part looks like this: # "fund" is a matrix of open, high, low, close, and volume prices returns <- function(fund) { p_12ago = as.vector(fund[nrow(fund)-252,6])

Dear R helpers, I have two input files as 'quantity.csv' and 'equity_price.csv' as (for example) given below. 'quantity.csv' GOOG     YHOO 1000         100 'equity_price.csv' sr_no   GOOG_price           YHOO_price 1            15.22                 536.40 2            15.07                 532.97 3            15.19                 534.05  4

Hi, As I mentioned some time ago on the mailing list, I'm working on the implementation of the Sarkar's Extended Linear Scan algorithm for LLVM. For testing and debugging of this algorithm, I need some good test-cases that check different functionalities of the register allocator, e.g.: - test-cases involving a lot of spilling - test-cases using pre-colored registers, e.g. like the EAX

Please, Where can I find a list of repositories all over internet.. I want to keep my CentOS servers up 2 date with mailscanner, clamAV, syslog-ng, and others... I know dag has a very goog one but there are some paktes I can not find in dag repository like mailscanner, syslog-ng, among others... Sorry if it's offtopic but I need it!
