I apologize if this seems obvious, but I have only been working with R studio for a couple of days.
I am trying to run a head function in R Markdown off of a dataset I imported for a project:
The code so far is this:
daily_activity <- read_csv("dailyActivity_merged.csv")
daily_calories <- read_csv("dailyCalories_merged.csv")
daily_intensities <- read_csv("dailyIntensities_merged.csv")
daily_steps <- read_csv("dailySteps_merged.csv")
daily_sleep <- read_csv("sleepDay_merged.csv")
weight_log <- read_csv("weightLogInfo_merged.csv")
head(daily_activity)
When I run the head function, I get the following error:
Error: ! object 'daily_activity' not found
I'm obviously doing something wrong. What are my options to fix this?
Thank you in advance. I also apologies if this was hard to read. I'm not quite familiar with the formatting yet.

Hi @spbynum ,
Certainly!
head(daily_activity)
Id ActivityDate TotalSteps TotalDistance TrackerDistance LoggedActivitiesDistance VeryActiveDistance
Apologies for the formatting. I'll add a picture for good measure.
Are you running the head(daily_activity) command using the Ctrl + Enter key shortcut? Remember, that particular shortcut only runs the current code line not the previous ones so maybe you need to run daily_activity <- read_csv("dailyActivity_merged.csv") first.
Thank you for your reply! Please forgive my ignorance, but how might that look in a syntax format?

Your csv looks fine.
There are multiple possibilities of what can go wrong:
as @andresrcs pointed out maybe you are calling head(daily_activity) to inspect it without first calling the previous chunk (eihter clicking on the green arrow above the chunk or selecting it and hitting ctrl + enter)
since you didn't share your R markdown document - something like
---
title: "Posit 188830"
author: "spbynum"
date: "2024-07-07"
output: html_document
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
library(readr)
```
## First header
```{r}
daily_activity <- read_csv("dailyActivity_merged.csv")
```
## Second header
```{r}
head(daily_activity)
```
we can't see if you accidentally set something like
```{r, eval = FALSE}
daily_activity <- read_csv("dailyActivity_merged.csv")
```
which would cause the error since it means show the code but don't execute it - leading to the next chunk
```{r}
head(daily_activity)
```
not knowing about a daily_activity variable.
Providing the R markdown file (in a condensed way) would help.
I see what you mean. I appreciate the help. I’ll give it a try later today and report back!

It looks like it worked! I was not running the codes in the r markdown document, thinking that running the codes elsewhere was supposed to work here. I was mistaken.
I appreciate all your help! Working through this on my own can be a bit of a slog.
