similar to: R Programming help needed - Returning dataframes + 2 Variables dynamically

Hi, That was very useful information. Thanks. But still I am not able to get the desired output with updated code. Kindly help if you have any further thoughts ... Updated code : x <- 0 y <- 0 Logic_fn <- function(x,y){ print("Passed Values") print(x) print(y) x <- x + 1 y <- y + 1 print("After addition :") print(x) print(y) test_data <- rbind(x,y)

c() is used for constructing vectors. Or in other words using the method c(x,y) provides a vector of length 2 (hopefully). Therefore, you are pushing a single vector to your function and not two arguments as you want. It should be Logic_fn(x,y) not Logic_fn(c(x,y)). Furthermore, i would recommend reading up on how function constructs work. Two return statements within a function are redundant

The returned values are in the list you assign to test_data, the original x and y are not modified, i.e the returned value for x will be test_data[[1]] and for y will be test_data[[2]]. Using the same variable names in the function and test is perhaps what is leading to confusion. > On 28 Jul 2017, at 09:13, Vijaya Kumar Regati <VijayaKumar.Regati at m3bi.com> wrote: > > Hi, >

I have a dataset that has many columns which are NA or constant, and so I remove them like so: same <- sapply(dataset, function(.col){ all(is.na(.col)) || all(.col[1L] == .col) }) dataset <- dataset[!same] This works GREAT (thanks to the r-users list archive I found this) however, then when I do my data sampling like so: testSize <- floor(nrow(x) * 10/100) test <-

Hi All, This might be simple question, I need to retrive data for modelling from the databases. Eveytime date values changes so I countnot fix date value in the code, it is required to pass as parameter. When I pass the date as parameter, it throws error. (ERROR: column "start_dt" does not exist Position: 285) My script is as below, please guide me where am I going wrong? All parameters

Hi all, I am wondering in R, suppose I did the principal component analysis on training data set and obtain the rotation matrix, via: > pca=prcomp(training_data, center=TRUE, scale=FALSE, retx=TRUE); Then I want to rotate the test data set using the > d1=scale(test_data, center=TRUE, scale=FALSE) %*% pca$rotation; > d2=predict(pca, test_data, center=TRUE, scale=FALSE); these two

Hi everybody I wrote a couple of months ago about implementing the opus codec on a DK52 from Nordic (nrf52832 MCU, Cortex M4). In the meantime I got a bit further and would again like to ask some questions. My settings: I included all the opus files into my project (opus-1.2.1) Defined: FIXED POINT, VAR_ARRAYS, DISABLE FLOAT API, OPUS_BUILD, CELT_MODE_ONLY I am able to allocate enough memory

Buenas Alguien sabe como se hacen las predicciones de las series temporslea usando keras? Baaado en esto: https://tensorflow.rstudio.com/blog/time-series-forecasting-with-recurrent-neural-networks.html He intentado hacer un predict_generator(test_data) pero siempre me devuelve el error de que el array no coincid con las dimensiones Gracias!!

Hello! I am trying with this question again: I would like to test few distributional assumptions for some behavioral response data. There are few theories about true distribution of those data, like: normal, lognormal, gamma, ex-Gaussian (exponential-Gaussian), Wald (inverse Gaussian) etc. The best way would be via qq-plot, to show to students differences. First two are trivial: qqnorm(dat$X)

Es justo ese ejemplo el que estoy mirando, pero no sale la prediccion He probado a cambiar la funcion generadora, haciendo que devuelva como lista solo los input, pero sigue devolviendo error: Error in py_call_impl(callable, dots$args, dots$keywords) : ValueError: Error when checking model : the list of Numpy arrays that you are passing to your model is not the size the model expected.

Hi there! Here is the latest version of the series including Richard's comments. I also reworked the repository_main.ml code to avoid setting an empty entry if not found.

Hi, We have been using Samba File Server (Version 4.3.11 Ubuntu 14.04 LTS) for quite sometime now. We recently installed Samba-AD (Samba AD Version 4.7.6) and made the file server a member of the Domain. Everything was fine till around 11:15 am yesterday. We just added one more share folder and gave access to three users and restarted Samba File Server services - smbd, nmbd and winbindd -

Hey there, Here is an update of the series. The changes: * Incorporate Richard's comments. Left out the with_openfile one since that leads to a double close. * Change the ask option return type to string (removing the option) since if the use doesn't input anything we're using the default, and the default is now a mandatory parameter. * Make sure there are items in the

Hello all, I am trying to do factorial regression using lm() like this (example): model<-lm(y ~ x1 + x2 + x3 + x4 + x1*x2*x3*x4) The final term 'x1*x2*x3*x4' adds all possible interactions between explanatory variables to the model. i.e. x1:x2, x1:x2:x3, etc, etc. Now, the issue is that some of the interactions are significant and some are not. I can manually remove

Hi everybody! I would like to export the results of a test statistic in a *.csv file, but get an error. The code is below. The data are attached as .txt with tab as separator.

I also attached a txt with the output (copy/paste) in case that helps. ---- > library(WRS) >

Hi: Thank you very much for creating this very useful program. I downloaded the DOS version because there was a suggestion in th isolinux website. I was not able to detect the cd-rom on my pentium II computer with Award BIOS 4.51 v 1.10. I tried to set the IDE i/o address but I am not sure where to get the i/o address information. I used the i/o address in the Win98 device manager IDE
