Re: [R] How to pass a variable to a function which use variable name as a parameter

One way to use variable names in functions like Predict() that do not evaluate their arguments in the standard way is to use do.call() along with as.name(). E.g., varName<-"age" do.call("Predict", list(fit, as.name(varName), np=4))}) gives the same result as Predict(fit, age, np=4) Bill D

[R] How to pass a variable to a function which use variable name as a parameter

There are functions which use variable names as parameters in some R packages. However, if the variable name is stored in another variable, how can I pass this variable to the function. Taking the "rms" package as an example: library(rms) n <- 1000 age <- rnorm(n, 50, 10) sex <- factor(sample(c('f
