similar to: extract rows in dataframe with duplicated column values

Hi I want to extract a row from a data.frame but I want that object to be a vector . After trying some different ways I end up always with a data.frame or with the wrong vector. Any pointers? x <- data.frame(a = factor(c('a',2,'b')), b = c(4,5,6)) I want to get "a" "4" I tried: as.vector(x[1,]) a b 1 a 4 (resulting in a data.frame even after in my

Dear R-listers: I want to import a reasonably big file into a table. (15797 x 257 columns). The file is tab delimited with NA in every empty space. I have reproduced what I have used as my read.table instruction. I have read the R-dataImportExport FAQ and still couldn't solve my problem. (I might have missed it, of course). I'm using R.2.01 in a Mac G4, 10.3.7. I can import the

Hi I have two basic questions, and here they go, but I was wondering as well where can I ask these basic questions without bothering you people I've used Splus and now I'm using R and there's some functions that I can't simply find one: sort.col that allows data.frames to be sort by a given col (I saw the funtion sort but that's for vectors. and I can't believe I

Hi to you all My question is: there is a package written in UNIX for which there is no Mac version. I would like to know if it's possible to install the R UNIX version on the MacOSX and run that UNIX package on my Mac (through this UNIX R Vresion on a Mac) I have seen a porfile for r version 1.8.1 on darwin: http://r.darwinports.com/ is that it? aother question related to that if it's

Hi a) I want to make a list out of a data.frame, where each element of the list is a column of the data.frame. I looked in the archives and saw a lot of postings but surprsingly none elucidated me. I also tried the split, aggregate help files and counldn't see any easy way to do this. I wouldn't be surprised if it's there, but I really didn't see it. I solved the problem

Hi I have a data.frame with 2 columns. The first column is an ID column. The other columns are description of the ids. There is more than one description for each Id. Want I want to get as a value is a data.frame where each row corresponds to one ID and has as many columns as different descriptions. I have used a very convoluted step, but I'm very convinced there is an easier way to do

Very interesting topic. "What I want to know is *WHY* people are doing this?" Here goes my view - I've used many for loops, and each time I realize how stupid that is... AFTER I learned how to avoid it. But it's difficult to avoid them without knowing how to do it. (Monsieur de LaPalice wouldn't have puted it better...) For loops are conceptually very easy to understand.

I am trying to make a graph with 4 scatter matrixes plots and couldn't do it. While trying to find a solution for this I also came across the idea of giving different values to the same argument for each of the lower and upper function but couldn't do it. (Examplified below with the col argument). The first problem of plotting 4 scatter matrixes in a graph is a problem of real

Hello all, I want to extend a draggable object so it has one more attribute (type attribute, so I can distinguish different draggable types). Can anyone tell me how to do it?

I use Centos 7.6.1810 in my server with nut-2.7.2-4.el7.x86_64 which contains Solis version 0.60 08/18/2005, my last version. My hardware related by upsc is Microsol Solis 1.5, the same used to develop the driver. It's an ancient nobreak, but i still works, by the way, an excellent hardware, using the third set of batteries. If you need more information, please let me know. Greeting, Silvino.

Hello everyone, I am using the Asterisk REST API in order to establish a call to an endpoint and to send over a remote file (HTTP). The issue is that I am experiencing an audio quality issue. I have tried encoding the file differently, but everytime Asterisk is cutting the audio frequencies above 4Khz. The call is established with G.722 and the audio file is mono 16Khz 16 bit sln16 extension.

Dear R-Help List, I am using optim, with method=L-BFGS-B, to maximize a likelihood inside a large simulation exercise. This runs fine for most simulated data sets, but for some reason, about 1 out of 100 times, optim will just hang. Using a dumb approach to the problem (i.e. printing the parameter values each time the function being maximized is evaluated), I tracked down when this happens,
