Data frame creation with dynamically assigned variable names

225 Views Asked by At

I'd like to assign a value to a variable the name of which is determined on the fly, and then assign that variable to a column of a data frame, something like:

x = rnorm(10)
y = 'z'
data.frame(assign(y, x))

While assign(y, x) creates z with the right values, it fails to name the data frame's column "z".

Based on the OP comment, the solution would be:

#Code
assign(y, x)

For the other issue you can try:

#Code2
df <- data.frame(assign(y, x))
names(df)[1] <- y

Output:

df
            z
1  -0.5611014
2  -2.2370362
3   0.9037152
4  -1.1543826
