Re: [R] convert numeric variables to factor

2018-04-10 Thread PIKAL Petr

Hi
You could instead of selecting columns by name select them by number

Something like
your.data[,2:3] <- do.call(data.frame, lapply(your.data[,2:3], factor))

or you could construct a vector of column numbers

x <- c(2,3)

Cheers
Petr

Thank you very much.

After that I have the following error:

cols<- c("GrMM", "RELG", "CASTE1", "SECTOR", "SECTOR4","AGE", "MARITAL", 
"JOBSTATUS", "ENG", "EDU", "PARENT_EDU", "MASSMEDIA_F", "MASSMEDIA_M",

Error in sort.list(y) : 'x' must be atomic for 'sort.list'
Have you called ‘sort’ on a list?

First, please post reproducible examples; your code will not run in anyone 
else's session (for example you have not shown where the data frame comes 
from), and if the code does not generate the error message reproducibly, noone 
can tell you exactly why it happens

Second, please _follow_ the posting guide and work through the suggested steps 
before posting a question to this list. An internet search for this error would 
have told you what causes it.

Finally: 
- Your loop will not work because your loop variable is I and the index is i; 
they are different in R. You'll just update the same column (i) lots of times, 
assuming i is defined.

- The error message arises from a call to factor() in as.factor(). It tells you 
that the column being converted is not a simple vector. That in turn tells me 
that you have not constructed your data frame correctly. I can't tell you what 
you did wrong there. 

- As another poster has said, data.frame is the name of a function - one that 
construicts a data frame. R can often tell which you want, but it is never safe 
to use the name of a function as the name of a data object. Use a different 
name for your data frame.

Re: [R] convert numeric variables to factor

Not sure whether this is the problem but calling your data frame 
data.frame is not a good idea.

Re: [R] convert numeric variables to factor

Hello,

Though Bert's and David's answers are what you should do, note that some 
R functions that need factors will coerce their input variables when 
necessary.
Have you tried to run the code you haven't posted without coercing to 
factor? It might run...


Hope this helps,

Or use cut():

> Num <- c(2.2, 2.4, 3.5, 5, 7)
> cut(Num, breaks=c(0,2,4,6), labels=c("Low","Medium","High"))
[1] Medium Medium Medium High
