Chi square test in loop

[gtmbini]

I am trying to do chi-square test with a bunch of variables but I am getting errors. Could you please help me with this?

When I just work one by one it works. However, it is not working when I am using it in lapply. Does missingness is the main issue? How can I deal with this? Please see the code below:

> chisq.test(data$gender, data$crclgroup2_1mo)

Pearson's Chi-squared test with Yates' continuity correction

data: data$gender and data$crclgroup2_1mo
X-squared = 0.14166, df = 1, p-value = 0.7066

factor_variables <- c("gender", "race")
lapply(data[, factor_variables], function(x) chisq.test(data$crclgroup2_1mo, x))

Error is: Error in stats::chisq.test(x, y, ...) :
'x' and 'y' must have the same length

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.…
