how to truncate data

[akashawalker]

Hi to all
I am a beginner to R Studio and i am really enjoying learning the coding.
i have a simple question, i have a data file with only 2 variables. and I want only to plot data until a certain value.
Like i want to truncate the data to the maximum value of one of the variable .
maybe the word truncated is not the correct word, but i want to create a new set of data, when variable x is a maximum.

Any help

Hi Sofia, welcome!, is better if you make your questions with a REPRoducible EXample (reprex) but here is an example with some built-in data

library(dplyr)
library(ggplot2)

sample_data <- iris[,c("Sepal.Width", "Sepal.Length")]
sample_data %>%
    filter(Sepal.Length <= 4.6) %>% # Filtering up to a maximum value
    ggplot(aes(Sepal.Length, Sepal.Width)) + # Ploting the result 
    geom_point()

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…
