Dear all, Hope you are doing great. I am currently using R version 3.4.1 ("Single Candle") and was trying to install packages RODBC and RODBCext using the following steps: > install.packages("RODBCext") Installing package into ?C:/Users/PaulBernal/Documents/R/win-library/3.4? (as ?lib? is unspecified) also installing the dependency ?RODBC? trying URL '

I don't use Windows, but this looks like a Windows permissions issue, no? You could try moving them yourself manually or create another library directory that R can access to put them in. ... or wait and hope for advice from someone who uses Windows to give you a definitive answer. Cheers, Bert Bert Gunter "The trouble with having an open mind is that people keep coming along and

Hi Paul, I recently ran into file path conflicts and found the following useful (looks like you already know the answer to 1.): 1. Use .libPaths() to find where packages are being stored. 2. To change this path: Control Panel > search ?View advanced system settings? > Environment Variables *button *> a. *Edit* current R_LIBS_USER to new file path b. *New*

Dear Leslie and Thierry, Thank you so much for your kind and extremely valuable replies. Only one doubt remains, which path do you think is the best option to store downloaded packages? Should I set it up so that all installed packages are in the same folder (path) that I installed R? Or can I simply set it up so that all installed packages are stored in a different path? Again, thank you guys

Dear Paul, We install R in C:/R/R-x.y.z and packages in C:/R/library. This makes the packages location independent from the R version. Best regards, ir.

Dear R friends, I am currently using Windows 8, 64-bit operating system, x64-based processor. I have installed R version 3.4.1 "Single Candle". Also, I have several packages installed in this path: C:\Users\PaulBernal\Documents\R\win-library\3.4 Plus some other packages installed in this other path: C:\Users\PaulBernal\Desktop\DESTOP FILES\R Books C:\Users\PaulBernal\Desktop\DESTOP

Dear Paul, Maybe some of the packages were installed by a user with admin rights and you are installing them with a user how has no admin rights. Thus you have no rights to remove the files created by the admin user. We made clear to our IT departement that they only may install R and not additional packages. We also tell them to set the environment variable R_LIBS_USER to C:/R/library and make

Basic algebra and exponentials/logs.

Dear Bert, Thank you for your extremely valuable feedback. Now, I just want to understand why the signs for those starting values, given the following: > #Fiting intermediate model to get starting values > intermediatemod <- lm(log(y - .37) ~ x, data=mod14data2_random) > summary(intermediatemod) Call: lm(formula = log(y - 0.37) ~ x, data = mod14data2_random) Residuals: Min

Possibly so. However, the ZeroMQ libraries do exist for Windows, so it might be possible to get the package working there. However, CRAN probably won't have the libraries, so cannot produce a binary package, and it is also quite possible that the package author is not a Windows person. At the very least, you'll need some familiarity with the Windows toolchain and be prepared to apply a

Dear Bert, Thank you so much for your kind and valuable feedback. I tried finding the starting values using the approach you mentioned, then did the following to fit the nonlinear regression model: nlregmod2 <- nls(y ~ theta1 - theta2*exp(-theta3*x), start = list(theta1 = 0.37, theta2 = exp(-1.8), theta3 =

Hello everyone, I was reading a table into R, and when trying to retrieve it the following message appeared: [ reached getOption("max.print") -- omitted 469376 rows ] Does this mean that R left out 469376 rows? Or R is taking those 469376 rows as well and the limitation is only for printing purposes? Thanks in advance for any help, Best regards, Paul [[alternative HTML version

Oh, sorry; I changed signs in the model, fitting theta0 + theta1*exp(theta2*x) So for theta0 - theta1*exp(-theta2*x) use theta1= -.exp(-1.8) and theta2 = +.055 as starting values. -- Bert On Sun, Aug 20, 2023 at 11:50?AM Paul Bernal <paulbernal07 at gmail.com> wrote: > Dear Bert, > > Thank you so much for your kind and valuable feedback.

Dear R friends, I am currently working with time series data, and I have a table(as data frame) that has looks like this (TransitDate are in format = "%e-%B-%Y") : TransitDate Transits CargoTons 1985-04-01 100 2500 1985-05-01 135 4500 1985-06-01 120 1750 1985-07-01 100 3750 1985-08-01 200

Hi Paul, #First I set up some sample data since I don't have a copy of your data dtOrig <- as.Date( c("1985-04-01","1985-07-01","1985-12-01","1986-04-01")) dfOrig <- data.frame( TransitDate=dtOrig, Transits=c(100,100,500,325), CargoTons=c(1000,1080,3785,4200) ) #Generate the complete set of dates as a data frame dfDates<- data.frame(

I got starting values as follows: Noting that the minimum data value is .38, I fit the linear model log(y - .37) ~ x to get intercept = -1.8 and slope = -.055. So I used .37, exp(-1.8) and -.055 as the starting values for theta0, theta1, and theta2 in the nonlinear model. This converged without problems.

Dear all, Hope you are doing great. I have a .csv file that I read into R, the .csv file consistss of two fields (TransitDate and CargoTons). The TransitDate I formatted from Excel in the fashion mmm-yy (e.g.: Apr-2013). However R does not recognize the field TransitDate as a date field. Here is the code: library(lubridate) Dataset <- read.table("U:/NEWCargoData.csv",

Dear friends, I am currently using R version 3.4.2 (64-bit for Windows) and when trying to download package rggobi an error pops up with the following message: "The program can?t start because libxml2-2.dll is missing from your computer. Try reinstalling the program to fix this problem" Is this suggesting me to reinstall R or is there a way to get the libxml2-2.dll somewhere to solve

Hi Bert, Below the information you asked me for: nrow(mydataset) [1] 2986276 ######## sapply(mydataset, "class") $`Transit Date` [1] "POSIXct" "POSIXt" $`Market Segment` [1] "character" $`N?mero de Tr?nsitos` [1] "numeric" $`Tar No` [1] "character" $`Beam Range (Operations)` [1] "character" $`Operational Vessel Ranges

Dear Eric, Hope you are doing great. I also tried the following: #First I created the complete date sequence TransitDateFrame <- data.frame(TransitDate=seq(as.Date(dataset1[1,1]), as.Date(dataset1[nrow(dataset1),1]), by = "month")) #Then I did the merging dataset1NEW <- merge(TransitDateFrame, dataset1, by="TransitDate", all.x=TRUE) Now it has, as expected the
