问题 I have a model in R that includes a significant three-way interaction between two continuous independent variables IVContinuousA, IVContinuousB, IVCategorical and one categorical variable (with two levels: Control and Treatment). The dependent variable is continuous (DV). model <- lm(DV ~ IVContinuousA * IVContinuousB * IVCategorical) You can find the data here I am trying to find out a way to visualise this in R to ease my interpretation of it (perhaps in ggplot2 ?). Somewhat inspired by

问题 There are several posts regarding the same, but i still not able to make my expect script work properly. My intention is to automate everything but leave the password enter for the user. So there are 3 parts of the script: automated login give the user interaction to enter the password give control back to Expect script to continue work So i have script which will be spawned and which have 3 read commands. First and last should be filled by Expect and second one i would like to enter my self:

问题 I have an x-matrix of 8 columns. I want to run glmnet to do a lasso regression. I know I need to call: glmnet(x, y, family = "binomial", ...). However, how do I get x to consider all one way interactions as well? Do I have to manually remake the data frame: if so, is there an easier way? I suppose I was hoping to do something using an R formula. 回答1: Yes, there is a convenient way for that. Two steps in it are important. library(glmnet) # Sample data data <- data.frame(matrix(rnorm(9 * 10),

问题 I'm trying to conduct a simple slopes analysis for a mixed effects model obtained with lmer . The model is similar to the following: data(Orthodont,package="nlme") mod <- lme4::lmer(distance ~ age*Sex + (1|Subject), data=Orthodont) When trying to conduct a simple slopes analysis with the function sim_slopes in the package interactions , I obtain the following error message. interactions::sim_slopes(model=mod, pred=age, modx=Sex) Error: One of the requested columns does not exist. Backtrace: 1

问题 I have a python application which I cant edit its a black box from my point of view. The python application knows how to process text and return processed text. I have another application written in Java which knows how to collect non processed texts. Current state, the python app works in batch mode every x minutes. I want to make the python processing part of the process: Java app collects text and request the python app to process and return processed text as part of a flow. What do you
