similar to: reshape without timevar argument?

Dear R-list, I am having troubles selecting rows from a very large data-set containing distances between capitals. The structure of the data-set looks like this: numa ida numb idb kmdist midist 1 2 USA 20 CAN 731 456 2 2 USA 31 BHM 1623 1012 3 2 USA 40 CUB 1813 1130 I want to select a subset of these dyads, and have

Hello, Apologies if this is the wrong list, I am a first-time poster here. I have an experiment in which an output is measured in response to 42 different categories. I am only interested which of the categories is significantly different from a reference category. Here is the summary of the results: summary(simple.fit) Call: lm(formula = as.numeric(as.vector(TNFa)) ~ Mutant.ID, data =

I'm new to SAMBA and am trying to install it on a Origin 200 running IRIX 6.4. I’ve downloaded and un-tarred 5 files: samba samba.idb samba.man samba.src samba.sw Now what do I do? I’m really lost. I must be missing something. Any help would be greatly appreciated. Please respond to: krestoule@yahoo.com TIA!! -Kyle Restoule

Hello, I propose two small changes to spec.pgram to get modest speedup when dealing with input (x) having multiple columns. With plot = FALSE, I commonly see ~10-20% speedup, for a two column input matrix and the speedup increases for more columns with a maximum close to 45%. In the function as it currently exists, only the upper right triangle of pgram is necessary and pgram is not returned by

Hi all! I have data in ?Long? format which I would like to reshape to ?Wide?. I know that one possibility is the ?reshape? command, which needs a ?timevar?. Data look as follows: There are approx. 3000 persons (?IDENTITY?) and, for each person, there are between 2 and 20 events (?EVENT?). For now, there's one row for each event (9506 rows)

I have two waves of a survey given to students at various middle schools and high schools, with student id numbers for each student. I am having difficulty reshaping the file from long to wide. My code is below: library(foreign) svy <- read.spss("studsur4.SAV") svy.wide <- reshape(svy, timevar="WAVE", idvar="id", direction="wide")

Hello All, I was wondering if it's possible to reshape data from long to wide in R without using a "timevar". I've pasted some sample data below along with some code. The data are sorted by Subject and Drug. I want to transpose the Drug variable into multiple columns in alphabetical order. My data have a variable called "RowNo" that functions almost like a

Dear list, I've recently become interested in comparing the spectral estimates using the different methods ("pgram" and "ar") in the spectrum() function in the stats package. With many thanks to the authors of these complicated functions, I would like to point out what looks to me like a bit of an inconsistency -- but I would not be surprised if there is good reasoning

Hey folks, This is my first message to the mailing list so please let me know if I mess something up. I'm trying to use the selectcommand for the mclistbox but I'm not very adept at using functions. Ideally I'd like to change the editor text when a different list item is selected but any help using the selectcommand would be appreciated and I think I could get the rest working.

Hi all, This is the second take of a patch that I submitted some time ago for allowing specifying vcpu pinning taking NUMA nodes into account. IOW, something like this: * "nodes:0-3": all pCPUs of nodes 0,1,2,3;  * "nodes:0-3,^node:2": all pCPUS of nodes 0,1,3;  * "1,nodes:1-2,^6": pCPU 1 plus all pCPUs of nodes 1,2    but not pCPU 6; v1 was a single patch, this is

I am developing a package to analyse physiological time-series and I thought that the most reliable and robust solution was to base it on the native stats::ts class. In my domain it is common to express series frequencies as samples-per-second. So ts(..., frequency=10) would mean a signal sampled 10 times every second, and ts(..., frequency = 1) a signal sampled every second. Following this logic,

Hi. The description of na.contiguous says: "Find the longest consecutive stretch of non-missing values in a time series object. (In the event of a tie, the first such stretch.)" But this seems not to be the case if one of the tied longest stretches is at the start of the sequence/series. In the following example, there are three stretches of length 3, so I expect the result

It's been three months without an answer, is it ok to thread bump? Would someone provide a pointer? Thank you for your consideration, Johann On Mon, 16 Sep 2019 at 15:53, Johann R.

Hi, is there a function in R to convert data read with read.shape and which is originally in UTM coordinates into longitude / latitude coordinates? I found the convUL() function from the PBSmapping package but I have no idea how I could apply that to the read.shape object. Many thanks, Werner __________________________________________________ Do sragenden Schutz gegen Massenmails.

Hi all ! I don't know what else to do but I absolutely can't get it to work !!! :( I've installed 2.2.8a on my SGI 6.5.17 workstation and all the tests I've done failed. I'm getting quite desperate. :( Ok. Point by point I'll try to explain what I did. - Installed the 2.2.8a successfully and started it successfully. - Logged in the samba (almost) successfully from the

salutations! i am doing some longitudinal modeling with sem and thought calculating some "simple variables" would make my model more readable. this is the smallest subset of my model that illustrates the resulting problem. i have 2 observed exogenous variables (c1, d2) and 4 observed endogenous variables (dc1, dd1, dc2, dd2). c1 is the observed state at time 1, dc1 is the change in c

Dear all: I have a shapefile in UTM coordinate system and I would like to transform it to Lat/Log coordinates (WSG84). The package PBSmapping contains function convUL to transform between the two coordinate systems when data is in the form of a data frame with attributes specifying the coordinate system. However, when shapefiles are imported using function read.shape (package maptools), a list

Thank you for the quick follow up, Duncan. Unfortunately extend=TRUE is called internally in various instances such as when replacing parts of the time-series with window<-.ts Consider the following examples of time series with ugly values: x = 1:22 foo = ts(x, start = 1.5, end = 106.5, frequency = 0.2) # a ts of 525 cycles bar = ts(x, start = 2.5, end = 107.5, frequency = 0.2) # a ts of 525

I agree it's a bug, and agree with your analysis. You should report it on bugs.r-project.org. (If you don't have an account there, let us know, and either someone will give you one, or someone will report it for you.)
