similar to: Converting Multiple Columns of Data Frame to Date

Full_Name: John Bodley Version: 2.5.1 (2007-06-27) OS: Windows XP Submission from: (NULL) (12.144.182.66) I was fitting a number of time series in R using the stats::HoltWinters method to define a single exponential smoothing model, i.e., beta = gamma = 0. I came across an example where the fitted value of alpha was not defined in the [0, 1] interval which seems to violate the lower and upper

Thanks Jeff. This is a nice way of solving this problem. What about the cases with 0015-02-21?Many thanks.?Best,Farnoosh On Wednesday, June 28, 2017 10:49 PM, Jeff Newmiller <jdnewmil at dcn.davis.ca.us> wrote: I doubt your actual file looks like the mess that made it to my email software (below) because you posted HTML-format email.

I doubt your actual file looks like the mess that made it to my email software (below) because you posted HTML-format email.

Dear all, Sorry to post my query once again in the list, since I did not get attention from anyone in my previous mail to this list. Now I make it simple here that please give me a code for find out the columns of a dataframe whose correlation coefficient is below a pre-determined threshold. (For detailed query please see my previous message to this list, pasted hereunder) Thanks and regards,

I'm not sure why this is happening: tmp <- data.frame( a = letters[1:2], b=c(TRUE, FALSE), stringsAsFactors = FALSE ) idx <- matrix(c(1, 2, 2, 2), 2, byrow = TRUE) tmp[idx] [1] " TRUE" "FALSE" Notice there is a space before the TRUE: " TRUE". This space isn't happening purely because of coercion: c("blah", TRUE, FALSE) [1]

I'm having trouble getting RMySQL to load. I was able to build it and install it (RMySQL_0.5-11.tar.gz). I was also able to build and install mysql-5.0.37. I've read many postings about this but have not found a mention of my particular problem (some closely related). I get the "unable to load shared library, no such file" error, but all the files do exist, RMySQL.so and

I don't use MySQL but I have seen messages like this before. They often have replies which indicate that you need to follow the instructions more closely. I suggest you search the list for these previous posts as I'm sure there is help there, somewhere!

R-Devel, I store and retrieve a large amount of financial data (millions of rows) in a PostgreSQL database keyed by date (and represented in R by class Date). Unfortunately, I frequently find that a great deal of processing time is spent converting dates from character representations to Date class representations in R, presumably because strptime is not fast for large vectors (>10,000

I am using the following command to replace all the missing values and assorted typos in a dataframe with NA: mydata[mydata>80]=NA The problem is that the first column contains values which should be more than 80, so really I want to do it just for mydata[,2:length(mydata)] I can't seem to re-write the code to fit: mydata[,2:length(mydata)>80]=NA # no error message, but doesn't

Hi, I have 2 date vectors d1 and d2. d1 <- structure(c(14526, 14495, 14464, 14433, 14402, 14371, 14340, 14309, 14278, 14247, 14216, 14185), class = "Date") d2 <- structure(c(14526, 14509, 14488, 14466, 14453, 14441, 14396, 14388, 14343, 14333, 14310, 14281), class = "Date") I would like to create another dataframe with columns d1 and d2, where d1 is the original d1

Hi, I seem to be having trouble getting more than 10 hits from Index#search_each since upgrading to 0.10.2 (ie, this was working in 0.9.4). Maybe a bug, as the #search_each doesn''t seem to use the options parameter any more ?

Hi all, I found an unexpected behavior when I was trying to use the macro defined in "R_ext/Itermacros.h" to loop over an atomic vector. Here is a minimum example: C++ code ``` #include "R_ext/Itermacros.h" #define GET_REGION_BUFSIZE 2 //Redefine the macro since C++ is not happy with the implicit type conversion #define ITERATE_BY_REGION_PARTIAL(sx, px, idx, nb, etype,

Hi Jakob, I've a problem related to the commit #155362. Consider the following snippet: void bar(float* f) { ... } void foo(float* f, int idx) { int hi = idx>>3; int lo = idx&7; bar(&f[hi*8+lo]); // hi*8 + lo == idx bar(&f[hi*10+lo]); } Before 155362 revision InstCombine was able to optimize hi*8+lo to idx by applying following patterns: 1. hi*8 -> hi << 3

Notice also Additionally, since you're implementing a "mean" function you are testing against R's mean, you might want to consider that R uses a two-pass calculation[1] to reduce floating
