Hana, the "right" answer depends on exactly what you need. Here are three correct solutions. They use the same basic strategy to give different results. There are also other approaches in R to get the same outcome. You could use data_catigocal[i,j] and some for loops.
size1 <-50000
ngroup <- 10 # note that size1 must be evenly divisible by ngroup
group_size <- size1/ngroup
data_catigocal <-data.frame(c(1:size1))
data_categorical1<-data_catigocal
# create categorical vector using deciles
group_vector <- c('0-10','11-20','21-30','31-40','41-50','51-60','61-70','71-80','81-90','91-100')
data_categorical1$group_vn <-rep(group_vector,group_size)
option2 <- rep(group_vector, group_size)
option2 <- sort(option2, decreasing=FALSE)
data_categorical2 <- cbind(option2, data_catigocal)
option3 <- rep(group_vector, group_size)
option3a <- sample(option3, size1, replace=FALSE)
data_categorical3 <- cbind(option3a, data_catigocal)

I want Create a categorical variable using the deciles of the following data frame to divide the individuals into 10 groups equally.
I try the following codes
data_catigocal<-data.frame(c(1:50000))
# create categorical vector using deciles group_vector <-
c('0-10','11-20','21-30','31-40','41-50','51-60','61-70','71-80','81-90','91-100')
# Add categorical variable to the data_catigocal data_catigocal$decile <- factor(group_vector) # print data frame data_catigocal
can any one help me with the r code
Kind regards,
Hana
