Dear R-users, I would like to create a new data frame composed of 2 columns of another data frame. But it does not give me what I want... > casesCNST[1:10,] case X1 X2 X3 X4 expected 1 A1 0 0 0 0 E 2 A2 0 0 0 1 C 3 A3 0 0 0 2 C 4 A4 0 0 0 3 C 5 A5 0 0 0 4 C 6 A6 0 0 1 0 C 7 A7 0 0 1 1 C 8

Dear R-Users, A message to continue the discussions we had in March and June. I have read the documents written since then (http://www.r-project.org/doc/R-FDA.pdf ; http://user2007.org/program/presentations/harrell.pdf ; http://user2007.org/program/presentations/rossini.pdf ; http://user2007.org/program/presentations/soukup.pdf) which are very interesting and useful. I work in a CRO and we

I made an ANOVA with repeated mesures (aov(Mesure~Distance*Genre*Correct+Error(Sujet/(Distance*Genre*Correct)), data)) and I would like to extract the pvalues.

Does anyone know if for clinical studies the FDA would accept statistical analyses performed with R ? Delphine Fontaine

Dear Sweave-users, I want to print listing using sweave. Because my tables are very big, I use the longtable option. But, is it possible to recall the first line of the table (e.g the colnames line) on each new page ? Thanks for your help. Delphine

Dear guRus, I would like to loop over a medium amount of Sweave code, including both R and LaTeX chunks. Is there any way to do so? As an illustration, can I create a .tex file like this using a loop within a .Rnw file, where the "1,2,3" comes from some iteration variable in R? ################################################ \documentclass{article} \usepackage{Sweave} \begin{document}

Dear R-users, I would like to write Greek letters followed by subscripts in a graph (on the X-axis and in a legend).

Is this a fixed width format? If so, read.fwf() in base, or read_fwf() in the readr package will solve the problem. You may need to trim trailing spaces though.

hi Sarah, Thanks a lot for having taken time to answer me and for your reply. I wonder how I missed this solution. Indeed plotting the line with the 2 extreme data points works perfectly.

dear R users, I am performing a linear regression with lm, and I would like to plot the regressor in dashed lines. I know that the lty=2 option is the way out, but it has a very strange behaviour: the line starts dashed but then the spaces between each dash becomes very tiny and so the line become somehow continuous for the human eye. Do you know how to fix that problem, in order to have a

Hello I am the administrator of a server linux with 25 clients. Lasdt year : no problem. Each children saves files in the same directory on the server. But now, the teachers want that the children have different directories. Then 600 children have a directory on the server and each directory is secured by a password. When they want to save a file on the server, a lot of them may not open their

dear R-users, I am facing a quite regular and basic problem when it comes to dealing with datasets, but I cannot find any satisfying answer so far. I have a messy dataset of galaxies like that : And XVIII 000214.5+450520 0.69 17 9 0.00 -8.7 26.8 6.44 6.78 < 6.65 -44 0.5 MESSIER031 0.6 1.54 PAndAS-03 000356.4+405319 0.10 17 0.00 -3.6 27.8 4.38

Hi, It's because you are plotting a line between each of the points in your data frame, and they are very close together: > cbind(df1$B,predict(regressor,df1)) [,1] [,2] 1 1.410832 -13.96466 2 1.589383 -15.21169 3 1.446662 -14.21491 4 1.488665 -14.50826 5 1.487035 -14.49687 6 1.497347 -14.56890 7 1.458070 -14.29458 8 1.568134 -15.06328 9 1.543364 -14.89029 10 1.513473

Hi, I would like to simulate data with a binary outcome and a set of predictors that are correlated. I want to be able to fix the number of event (Y=1) vs. non-event (Y=0). Thus, I fix this and then simulate the predictors. I have 2 questions: 1. When the predictors are continuous, I can use mvrnorm(). However, if I have continuous, ordinal and binary predictors, I'm not sure how to simulate

I've got a data frame having numerical data by zip code: ZIP DATA 94111 12135.545 93105 321354.65654 94111 545.555 94706 558858.66 ... ... I'm using this function to group records by ZIP and calculate the median of DATA: aggregate(d$DATA, list(Zip = d$ZIP), FUN=median, na.rm=T) but what I really want to do is to calculate several statistics (median,

dear Jim, Yes I fixed the problem. Thanks again all of you for your contribution! This worked : start <- c(1, 20, 35, 41, 44, 48, 53, 59, 64, 70, 76, 78, 83, 88, + 93, 114, 122, 127) data1<-read_fwf("lvg_table2.txt",skip=70, fwf_widths(diff(start))) Well now I know how to deal with fixed-width files :) Cheers Jean-Philippe On 05/10/2017 18:42, jim

Hello, I'm trying to use the version 0.6 of chan_capi-cm for outgoing calls it works perfectly but for incoming calls it doesn't work. I tried to set an extension to dial my from-pstn context and it works. So I think there's a problem with my capi.conf or something... Here's a debug when calling -- CONNECT_IND (PLCI=0x101,DID=9100,CID=46720XXXX,CIP=0x4,CONTROLLER=0x1)

Hello, I am trying to translate a matlab program into R, and I have some problems to find out how to translate the PPVAL function. I know that ppval(pp,xx) returns the value at the points xx of the piecewise polynomial contained in pp( constructed by spline), but I don't know how to do the same thing in R. Thanks for you help Delphine

You should be able to use that header information to create the correct parameters to the read_fwf function to read in the data.
