Hello,
Thank you for your help, I really appreciate it, I was able to solve the
problem!
Here is a part of my dataframe (just in case...):
> dput( head( behavioral_df) )
structure(list(ID = c(1, 2, 3, 4, 5, 6), DOB = c("9/53/1959",
"4/8/1953", "2/21/1961", "10/11/1948", "9/4/1962", "8/22/1953"
Hi Anne,
As mentioned above, you may have to do nothing. Here is an example
that might clarify that:
azdat<-read.table(text="subject 1 2 3
1 10 20 30
2 11 22 33",
header=TRUE,stringsAsFactors=FALSE)
azdat
subject X1 X2 X3
1 1 10 20 30
2 2 11 22 33
As you can see, R simply prepends an
... and to add to what Eric and Duncan have said, what you have as column
names depends on how the data were imported. e.g.:
> d1 <-data.frame(a = 1:3, `1b` = letters[1:3]) ## check.names has a
default of TRUE
> names(d1)
[1] "a" "X1b" ## note the conversion to a syntactically valid name. See

Hi Anne,
It would be helpful to include at least part of behavioral_df for people to
understand the issue better.
Please do the following in R and post the output.
dput( head( behavioral_df) )
Also, set your email to plain text as HTML is stripped from emails on this
list.
Best,

Hello,
I think you have to use 'matches' instead of 'starts_with', I believe
starts_with does not accept a regular expression whereas matches does.

Dear R users,
I have a dataframe that contains several variables, among which 105
correspond to scores on certain trials. Unfortunately, when I imported this
dataframe into R, I realised that the variable names corresponding to each
trial begin with digits, which violates R naming conventions.
