as.numeric() change for some but not other

[Jason1]

Hello,
Here is something I couldn't figure out - when using as.numeric() to change the type of variables, which all are character, only a few of them did change but not all of them. below were the codes and results
final1<- within(final1, Bother <- as.numeric(Bother),
concentration <- as.numeric(concentration),
Depressed <- as.numeric(Depressed),
Effort <- as.numeric(Effort),
Hopeful<- as.numeric(Hopeful),
Fearful<- as.numeric(Fearful),
Restless<-as.numeric(Restless),
Happy <- as.numeric(Happy),
Lonely <- as.numeric(Lonely),
Not_Get_Going<-as.numeric(Not_Get_Going)
)
only Bother, Effort, Fearful, and Happy did change, but the rest of them did not.
Thanks in advance for help!
Jason

Check whether the variables that don't change all have valid numbers.

Can you provide a reproducible example of the dataset?

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.…

The problem has been fixed now with using the following function
data[,'variable'] <- as.numeric(data[,'variable'])
Thanks for everyone support!
