How can I access all objects of class data.frame inside .GlobalEnv in R

Question

I have 8,000 data.frames inside my global environment (.GlobalEnv) in R, for example

head(ls(.GlobalEnv))
#[1] \"db1\" \"db2\" \"db3\"          


        

Answer 1

I have found another solution:

db1 <- data.frame(x = c(1,2,3),y = c(1.1,1.2,1.3))
db2 <- data.frame(x = c(1,2,3,4),y = c(2,2.1,2.2,2.3))
db3 <- data.frame(x = c(1,2,3,4,5),y = c(3,3.1,3.2,3.3,3.4))
ls()
#[1] "db1" "db2" "db3"
nombres <- ls()
eval(parse(text = nombres[1]))
#  x   y
#1 1 1.1
#2 2 1.2
#3 3 1.3
lm(y~x,data = eval(parse(text = nombres[1])))

Thanks!
