formula

问题 I was wondering if there is anyway to return the name of the table using a formula? I was working on a way to break down a few thousand addresses into there perspective column of information. ie.. #, Street, City, State, Zip-code and Phone#.

问题 I have a large dataset stored in a long dataframe. I would like to extract data on some variables and use a formula to generate new data. All the necessary information should be extracted from the formula. First, I want to use the information in the formula to filter the dataset for the according variables - I use the all.vars() function for that. I also rely on the formula.tools package, which is on CRAN. It is used for easy extraction of the left and right hand side of the equation ( lhs

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 need to write a formula in Excel to look up specific words and write a string into a field depending on them. However, after first tries I realized that every formula I entered is displayed as false. So I even tried the most simple ones as: =SUM(H20, B11) But still, it causes syntax errors. Is something wrong with my Excel? Here is a screenshot of the error that always shows up: 回答1: Settings in Excel are important, because they affect functions. Anyways, the easiest way to know what kind

问题 I had already asked a question like this before but I'm really bad at VBA formula. Here is my formula: Worksheets("Sheet1").Range(CellRange).formula = "=IF(Sheet2!E$4=X;CONCATENATE(Sheet3!

I've used to follow the explanation from my previous question A question with a really good answer But It didn't worked this time. Any suggestions? Thank
