In the first line, use the dist function, found in library mva, to get the distance between each pair of rows. From this calculate an incidence matrix for which element i,j is true if row i in dat equals row j in dat (and false elsewhere). In the second line, for each row calculate the indices of the matching rows and take the minimum of those as the key. incid <-

I noticed the same thing as I reported below, when I upgraded from R-2.0.0-alpha-20040918 to today's beta version: 'R CMD check' failed as before; but after cleaning 'src' from .o and .so files, it worked again. So the two-day-old '.so' file is obviously different from today's. Has compiler directives changed in the two last days? Or what is happening? G?ran On

I find 'How do I convert factors to numeric?' in the FAQ (7.12), but not the other way around. Trivial maybe, but > codes(factor(c(2, 10)) [1] 2 1 > codes(factor(c(2, 9))) [1] 1 2 How do I get the levels attached to the codes in numeric order?

I need to order a long vector of integers with rather few unique values. This is very slow: > x <- sample(rep(c(1:10), 50000)) > system.time(ord <- order(x)) [1] 189.18 0.09 190.48 0.00 0.00 But with no ties > y <- sample(500000) > system.time(ord1 <- order(y)) [1] 1.18 0.00 1.18 0.00 0.00 it is very fast! This gave me the following idea: Since I don't care

I'm not sure from reading the documentation whether strptime(x, "%j") is meant to be supported, but if so, there is a bug which prevents it from working on the first day of months after

Hello. I noticed that when reading data with ov_read_float(), you can get values outside [-1..1] when the stream is encoded at lower quality, but with higher quality, the values trim down to inside [-1..1]. Looking at the plot from -q10, the data from ov_read_float seems clipped. I've made some plots of encoding the start of Rammsteins Feuer from the xXx soundtrack (it's a pretty loud

In my thought utc_offset function in src/lib/utc-offset.c returns wrong offset value when the year in localtime and GMT different. /* max offset of 24 hours */ if (ltm.tm_yday < gtm.tm_yday) offset = -24 * 60; else if (ltm.tm_yday > gtm.tm_yday) offset = 24 * 60; else offset = 0; I think this code should be modified as followings. /* max offset of 24 hours */ if ((ltm.tm_year ==

Hi In rtc_set_time, mktime is called to calculate seconds since 1970/01/01, input parameters of mktime are required to be in normal date format. Such as: year=1980, mon=12, day=31, hour=23, min=59, sec=59. However, the current input parameter of mktime is tm->tm_year, and it is the number of years since 1900. (For example, if current time is 2012/12/31, and tm->tm_year is 112). This is

Dear R-helpers, In a data set I got from a medical doctor there are six treatment groups and (about) 5 bivariate responses in each group. Using 'manova', it is easy to see significant differences in treatment effects, but the doctor is more interested in the correlation between the two responses (within groups). I'm willing to assume a common value over groups, and one way of

A few days ago I uploaded to CRAN a new package called 'eha', which stands for 'Event History Analysis'. Its main focus is on proportional hazards modeling in survival analysis, and in that respect eha can be regarded as a complement and an extension to the 'survival' package. In fact eha requires survival. Eha contains three functions for proportional hazards
