Hello: I use R with MAC I have a simple data table, numeric and text columns, named dt. The table is imported through read.csv from a csv file. Row numbers are automatically assigned, header is set to TRUE. there are 599 rows and several columns. I am trying to plot using the stripchart command: one numeric variable (say dt$fnatg) vs a text column (say dt$pat). dt$pat contains one of 3 values:

Friends, I am doing a URL classification, based on certain key words whether it contains an executive information or not. I have already went through 50K URL's and identified the key words and made it as 0, 1 ( 0 - do not have the key word and 1 - have the key word) and 0- do not contain executive information 1 - contains executive information. A sample set of data is shown below. DomainID

Hi everyone, We have been trying to construct a Lasso-cox model with discrete time. We conducted follow-up examinations on the epileptic attack after tumor surgical resection among glioma patients. The patients are followed-up in the 6/12/24 months after surgical resection, which makes the epilepsy-free time discrete (6/12/24 months). We calcluated many features from the T2-images

Hi, I'm analysing the LLD code structure (aka architecture) and am trying to mold it into a component model. Currently I see 4 components: - Driver - ReaderWriter - Passes - Core I wonder if this is the order that they're supposed to be in, since there are also code dependencies upwards from: Core -> ReaderWriter Passes -> ReaderWriter ReaderWriter -> Driver For a

Dear all, I'm not able to solve easily the following simple problem. I really hope someone can give me some hints. I trained an svm (e1071). Now I'd like to show the results graphically. I used plot.svm and I'd like to add some other objects to the plot: points, (coloured) ellipses to indicate some intersting regions, curves, and so on... I tried to pass these as additional

The python3 bindings create unicode objects from application strings on the guest (i.e. installed rpm, deb packages). It is documented that rpm package fields such as description should be utf8 encoded - however in some cases they are not a valid unicode string, on SLES11 SP4 the following packages fail to be converted to unicode using guestfs_int_py_fromstring() (which invokes

Dear professor, I am currently using Design package and the cph formula for assessing multivariable analysis. I am tryng to get the C-index for my survival model based on Dxy coefficient. I am confused since there is a negative value. Do I need to used the absolute Dxy ? index.orig training test optimism index.corrected n Dxy -0.341357727 -0.344002740

Dear All, I have two questions regarding the use of the R2BayesX package for Bayesian analysis. First, is it possible to generate predictions based on the fitted model? According to Gelman and Hill (2007, pp. 361-363), there are at least two ways to do this in BUGS: (1) generate additional data points with the dependent variable coded as missing (and all the independent variables fixed at

Hello, I would like, if it is possible, to compare the effect of a variable across regression models. I have looked around but I haven't found anything. Maybe someone could help? Here is the problem: I am studying the effect of a variable (age) on an outcome (local recurrence: lr). I have built 3 models: - model 1: lr ~ age y = \beta_(a1).age - model 2: lr ~ age + presentation

...sing, say, "--prefix=/usr/local", it will default to "--prefix=/usr/local/ups" which has the advantage of putting everything in one directory. To clean up, you just delete /usr/local/ups. Cleaning up after a botched install to /usr/local is painful, either involving backups, or surgically removing files from bin/, sbin/, etc/, man/man?/, etc. -- Charles Lepple clepple at gmail

There have been some efforts recently to use clang-tidy or similar automated refactoring to make project-wide cleanups/improvements to the LLVM codebase that appear to me to be a bit out of character with the sort of changes & philosophies that have been applied in the past. I think there are a few issues at hand which I'll try to summarize: * Churn/blame-convenience: Previously, large

Dear Dushanthi, Please keep your e-mails on the R-Help list, where Michael has already given you some excellent advice. As Michael already explained, metafor can handle proportions, but does not have any specific functionality for categorical variables with more than 2 levels (at the moment). So, if it is logical and possible to do so, you could collapse the levels of the categorical outcome to 2

Hello all, I am developing an out-of-tree backend for a unique simd processor and I'm looking for a bit of help. In my current design, it's possible for a case to arise where I decide during instruction legalization that a fixed-sized array of vectors which has been initially allocated on the stack needs to be lowered into the vector register file. I have this design working for the case

Hello metafor users, I'm using metafor to perform a single-effect summary estimate of the raw proportion of patients experiencing a post-operative complication, and I'm interested in seeing if this proportion differs between the three most commonly used surgical techniques. The software is working as expected, but I would like to double check on the interpretation of my mixed-effect model

Hi Charles; I had nut working from before, but managed to lock up something and had to reboot. Nut is in the stuff to start at boot time, but is not now capable to being restarted with the nut script in /etc/init.d, claiming it is disabled: gene at coyote:/usr/src/nut-2.7.2/docs/man$ sudo service nut start * nut disabled, please adjust the configuration to your needs * Then set MODE to a

...re, and I'd really like someone to come up with a solution for that. Indeed, we're now slower than GCC, and that's a place that looked impossible two years ago. But I doubt reverting a few patches will help. For this problem, we'll need a task force to hunt for all the dragons, and surgically alter them, since at this time, all relevant patches are too far in the past. For the future, emailing on compile time regressions (as well as run time) is a good thing to have and I vouch for it. But I don't want that to become a tool that will increase stress in the community. > Not sur...

Since I read the list in digest form (and was out ill yesterday) I'm late to the discussion. There are 3 steps for predicting survival, using a Cox model: 1. Fit the data fit <- coxph(Surv(time, status) ~ age + ph.ecog, data=lung) The biggest question to answer here is what covariates you wish to base the prediction on. There is the usual tradeoff between too few (leave out something
