Hi, I'm a group of functions and I would like to create a package for load in R. I have created a directory named INE and a directory below that named R, for the files of R functions. A have created the files DESCRIPTION and INDEX in the INE directory. The installation from local zip files, in the R 2.3.0, results but to load the package I get an error like: 'INE' is not a

Hello, It is possible to return the path of the current working R-file (in execution)? Thanks, Rita Sousa. [[alternative HTML version deleted]]

I have a list called "tabs" that I would like to have the same structure as my list "eqSystem." The two look like they have the same format but they are different because when I look at their attributes, class(eqSystem[[1]]) is "call" but class(tabs[[1]]) is "formula". I want to have class(tabs[[1]]) as a call too. So what does "call" mean? And how

Hi everyone, I have different listboxes in the same toplevel window. The problem is, if I select (by left clicking) one of those listbox elements, the current selection in the other listboxes is cleared! Anybody knows how I can prevent this?

Dear List Members,I have 55 data frames, each of which with 272 variables and 267 observations. Some of these variables are blanks but the blanks are not the same for every data frame. I would like to write a procedure in which I import a data frame, see which variables are blank, and delete those variables. My data frames have variables named P1 to P136 and Q1 to Q136. I have a couple of

Hi, In order to avoid deep copies by passing large arguments to functions or returning values, I'm trying to do the assignment of variables in a given environment. The problem is when I try to assign a structure: a list for example. If I have: ind <- c("a","b") my idea is doing something like l <- alist() l[ind] <- as.list(c(20,40)) in a given

Hello, How I use the function as.svrepdesign without memory.size problems? desenho_npc_JK <- as.svrepdesign(desenho_npc,type="JKn") Error: cannot allocate vector of size 161.3 Mb In addition: Warning messages: 1: Reached total allocation of 1022Mb: see help(memory.size) 2: Reached total allocation of 1022Mb: see help(memory.size) 3: Reached total allocation of 1022Mb:

Hi all, I'm having some problems in loading libraries. I wonder if anyone can help me with this. I have created two libraries with the same name at different locations. I want to use both of them, one at a time. So I do: library(mylib,lib.loc1) (....) detach('package:mylib') library(mylib,lib.loc2) The problem is that, after this, the used library is still the one first loaded.

Hello R users! I have several data frames where some of the variables have many missing observations. For example, Q1 in one of my data frames has over 66% of its observations missing. I have tried imputation with mice but it does not work for all the data frames and I get the following message or a similar message to this: iter imp variable 1 1 Q1 Q2 Q3 Q4 Q5 Q6 Q7 Q8 Q9 Q10 Q11

Hello, I dont have root access but I would like to install several packages (gtk) in my home directory. Is it possible to install it via yum ? -- --- Get your facts first, then you can distort them as you please.--

hi, I use automounter to mount to many hosts /net/<hostname>/dir When the hostname is unavaliable it seems NFS gets stuck. I would like to set a NFS timeout (say 60 secs). If not available then error. I need to use hardmount but is there such a thing as NFS client timeout? -- --- Get your facts first, then you can distort them as you please.--

Hello! Happy Valentine's Day... After I loaded the package lattice in R, it did not work. Then when I closed R and restarted it, R started with an error message and here is the feedback that I got from the R Console: Loading required package: Hmisc Loading required package: survival Loading required package: stats Loading required package: graphics Loading required package: splines Error in

Dear List Members,I am trying to set up a large system of equations and I am trying to find a simple way to set up the list command under the package system fit. Here is the example from system fit and what I am trying to do: EQ1 <- Y1 ~ X1 + X2 + X4EQ2 <- Y2 ~ X2 + X3EQ3 <- Y3 ~ X2 + X3 + X4EQ4 <- Y4 ~ X1 + X3 + X4eqSystem <-list(form1 = EQ1, form2 = EQ2, form3 = EQ3, form4 = EQ4)

Is there a tunable to set NFS hard mount time out? For instance, if the server becomes unavailable for extended amount of time, say 1 hour. I would like to timeout after 30 secs. (Soft mount isn't an option, BTW) -- --- Get your facts first, then you can distort them as you please.--

Hello R Users! I have a data frame that has many variables, some with missing observations, and some that are correlated with each other. I would like to subset the data by dropping one of the variables that is correlated with another variable that I will keep int he data frame. Alternatively, I could also drop both the variables that are correlated with each other. Worry not! I am not deleting

Dear all, I am analysing growth data - response variable - using GAM and GAMM models, and 4 covariates: mean size, mean capture year, growth interval, having tumors vs. not The models work fine, and fit the data well, however when I try to compare models using AIC I cannot get an AIC value. This is the code for the gam model:

Hi, I’m using the svyby for total statistics, for example: svyby(~p_igov,~div_a,desenho_nps,svytotal,drop.empty.groups=TRUE,vartype =c("se","var","cvpct")) In the numerical variable p_igov (and others) I have many non responses but if I maintain the NA it doesn’t work. summary(base_nps$p_igov) Min. 1st Qu.

Hello everyone! I have a data frame of 136 variables with 270 observations. I would like to create a new data frame such that each element of that data frame contains the maximum value of the 6 prior lags of the initial data frame. So for example, if my original data frame, A, were A1=c(7.72, 7.94, 7.56, 7.54, 0.93, 0.59, 7.21, 8.00, 7.19, 7.57)A2=c(4.27, 3.70, 3.80, 3.67, 3.83, 3.95, 4.02, 2.06,
