Hi I'm trying to extract complete rows from a dataframe by group based on the maximum in a column within that group. Thus I have a dataframe: cvd_basestudy ... es_time ... _____________ study1 ... 0.3091667 study2 ... 0.3091667 study2 ... 0.2625000 study3 ... 0.3033333 study3 ... 0.2625000 __________ etc I can extract the basestudy and the max(es_time)

Hi All, I am running a scatter plot and trying to add a best fit line. I use an abline function, but get no line drawn over the points. I also get no error. I arm using V 2.10.0 on Windows 7. Here is my code, including the SAS transport file import: require (foreign) require (chron) require (Hmisc) require (lattice) clin <- sasxport.get("y:\\temp\\subset.xpt") attach(clin)

Hi, I've seen posts (but no answers) about clearing a file lock on a Samba share. Presumably this kind of thing happens when the program abnormally terminates and doesn't close its open files. I've got a file that smbstatus reports as: 1216 DENY_WRITE 0x20089 RDONLY NONE /shares/share1/Files/december.xls Fri Jan 12 12:51:30 2007 Trying to open this in Excel

Hi I have a long data set on which I want to do Bland-Altman style plots for each rhythm type Using ggplot2, when I use geom_hline with facet_grid I get an extra set of empty panels. I can't get it to do it with the "Diamonds" data supplied with the package so here is a (much abbreviated) example: > lvexs cvd_basestudy ecd_rhythm fixed_time variable_time 1 CBP05J02

I have some data which is censored and I want to determine the median. Its actually cost data for a cohort of patients, many of whom are still on treatment and so are censored. I can do the same sort of analysis for a survival curve and get the median survival... ...but can I just use the survival curve functions to plot an X axis that is $ rather than date? If not is there some other way to

Hi I'm sure this question has been asked before but I can't find it in the archives. I have a data frame which includes interval and ordered nominal results. It looks something like "Measured" "Eyeball" 46.5 Normal 43.5 Mild 56.2 Normal 41.1 Mild 37.8 Moderate 12.6 Severe 17.3 Moderate 39.1 Normal 26.7 Mild NULL Normal 27.9 NULL 68.1

I cannot seem to get this to work? I have weighted data points that I want to fit an sd-ellipse to, but the ellipse is not right? I have attached a .tiff of what I get. I'm wondering if it's not looking at my actual data, but taking the data from the example? I ask this because I don't know where "Title" comes from in the graph? Also, I want to put calcentre=FALSE, but if I

Device Manufacturer: NHS Device Name: Laser Senoidal 5000VA upsc output when the UPS is in normal condition: battery.charge: 100 battery.current: 0.4 battery.date: 12292015 battery.runtime: 00000 battery.runtime.low: 59940 battery.temperature: 00 battery.voltage: 163.4 device.mfr: NHS Sistemas de Energia device.model: Laser Senoidal 5000VA device.type: ups driver.name: gamatronic

I wasn't clear. battery.runtime.low is not a counter, but a value estimated in seconds that is decreasing conforming the battery is discharging. It's mean: How much time (in seconds) will be necessary until the battery achieve the depleted status ( http://www.networkupstools.org/protocols/sec.html#Estimated_Minutes ) . If the UPS don't have a load, this value will be higher than the

Below the answers: > This is the same as https://github.com/networkupstools/nut/issues/254 , right? Yes, this UPS is the same. > Does battery.runtime only get updated when on battery power, or is this with a different load? > battery.runtime.low: 59940 > battery.temperature: 00 Yes, this time time is updated on battery power, This is a dynamic counter that changes with a different

Hi With ggplot2 I can very easily create beautiful histograms but I would like to put two histograms on the same plot. The histograms may be over-lapping. When they are overlapping the bars are shown on top of each other (so that the overall height is the sum of the two). Is there any way to get them to display overlapping (with smaller value in front, larger value behind) so that the overall

I have recently started a new job at an NHS hospital in Scotland. Since I took up this post 6 months ago I have had an ongoing dispute with the IT secutiry dept. who refuse to install R on my computer. I previously worked in another branch of the NHS where R was widely used and yet there is nothing I can say which will persuade the IT dept here to even visit the website! With some help from our

Hello I need to check that the NHS numbers in my database are valid. I''m storing them as ten-digit strings: the first nine are the identifier and the tenth is a check digit. There are four steps to calculating the check digit (from http://www.connectingforhealth.nhs.uk/systemsandservices/nsts/docs/tech_nn_check_digit.pdf): 1. multiply each of the first nine digits by a weighting factor

Hi! I am using RHL 5.2 and Samba 2.0.2. I have the SAMBA acting as the PDC in the network where most of the clients are Win95. Earlier we had a Novell Netware Network and I decided to shift over to Linux/Samba. I am having trouble implementing certain shares. The exact problem is described below: I want ONLY 'nhs' and 'vhs' to have read only access to '/usr/iso9001/edp'

Hi I need some help getting results from multiple linear models into a dataframe. Let me explain the problem. I have a dataframe with ejection fraction results measured over a number of quartiles and grouped by base_study. My dataframe (800 different base_studies) looks like > afvtprelvefs basestudy quartile ef ef_std entropy CBP0908020 1 21.6 0.53 3.27

I might be missing something really obvious, but is there an easy way to locate all non-unique values in a data frame? Example mydata <- numeric() mydata$id <- 0:8 mydata$unique <- c(1:5, 1:4) mydata$result <- c(1:3, 1:3, 1:3) > mydata $id [1] 0 1 2 3 4 5 6 7 8 $unique [1] 1 2 3 4 5 1 2 3 4 $result [1] 1 2 3 1 2 3 1 2 3 What I want to to be able to get some form of data output

I had a problem with Samba 2.2.5 with the printers being permanantly paused to Windows machines. They could print OK - it was only the status that was wrong. The reason for this was because I had used the word office in the printer name / comment. This was causing the parser which recognises the printer status to find 'off' pausing the printer. A quick fix for this is to replace the
