If I have two dataframes: df1: df1 = pd.DataFrame({‘A’:[10,20,15,30,45], ‘B’:[17,33,23,10,12]}) A B 0 10 17 1 20 33 2 15 23 3 30 10 4 45 12 df2: df2 = pd.DataFrame({‘C’:[‘cat’], ‘D’:[‘dog’], ‘E’:[’emu’], ‘F’:[‘frog’], ‘G’:[‘goat’], ‘H’:[‘horse’], ‘I’:[‘iguana’]}) C D E F G H I 0 cat dog emu frog goat horse iguana How do I… Read More Combine and fill a Pandas Dataframe with the single row of another
I want to change column names of a data frame with a function. To overwrite my data frame with the new column names, I used assign(), which first argument has to be the name of the same data frame as a string. To get the name as a string, I used deparse(substitute(x)), which worked outside… Read More How to get the object name as a string inside a function in r
I thought this would be something simple to do, but I don’t think it’s possible, why is that? This is what I’m trying to do. console.log("hello") ? bool : ""; This gives me an error: Expected an assignment or function call and instead saw an expression. Not sure exactly what that means. >Solution : Yes.… Read More Is it possible to use ternary operator for console.log?
I’m trying to assign values to specific indices of a long list of vectors (in a loop), where each vector is specified by a string name. The naive approach testVector1 <- c(0, 0, 0) vectorName <- "testVector1" indexOfInterest <- 3 assign(x = paste0(vectorName, "[", indexOfInterest, "]"), value = 1) doesn’t work, instead it creates a… Read More Assign() to specific indices of vectors, vectors specified by string names
I’m stuck with something that should be very easy. I have been working with a function that I want to take a vector or single column of data and output a "color" depending on which range the value falls into. band_code <- function(x){ x <- x[1] if(x < (-0.25)){color <- "cold"} else if(x > (-0.25)… Read More Assign and save values based on function output in R
I’m having issues with giving a vector object names when the vector itself is retrieved by get. This is a very simple example of my problem. Obviously the object_names object here isn’t doing anything specific but in my actual script it just pertains to what actually goes into the scores and names objects and is… Read More Assigning names to a vector retrieved by get()
Is it an unusual design pattern to assign output of function to many variables? Imagine each variable below representing complex data, such as nested dictionaries. def step_1(): a = … … i = … return a, b, c, d, e, f, g, h, i def step_2(a, b, c, d, e, f): … return j def… Read More Assigning function output to many variables: good or bad practice
