Replace set of words with another set of words in R
It is a simple question. I have a list of country names. However, I wanted to change few names with correct names. So, I have two more vectors; one with names to be changed, and second with correct names. See the example:
subset in r based on multiple columns
Im not sure how to perform this type of subset. In the code below, I have 4 variables depth
in meters, group
, value
and cutoff
in meters. I interpolated the variables from death of 5 to the max depth.
Creating a subset that only includes columns that have a certain value in a certain vector
Input:
library(ISLR) data("NCI60")
How to randomly and evenly subset my data with rules
I have a dataset, which is a list of pairwise comparison stimuli I want to randomly and evenly allocate to subsetted groups, but with some rules.
The comparison data frame is as below:
Subsetting multiple values in a single variable into two groups
I want to do regression analyses on particular groups of values of a single variable which need sub setting eg:
subsetting in R gives empty data.frame
we found a surprising result from basic code in R. We search for answers online but found nothing.
Does anyone knows the reason of this result?
