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

Dear R users,
I wrote in the meantime a new function:
apply.html(html, XPATH, FUN, ...)
This function applies FUN to the nodes selected using XPATH. However, I
wonder if there is a possibility to use more simple selectors (e.g.
jQuery). Although I am not an expert with jQuery, it may be easi
... 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

> names(d1)

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

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.

Thanks, the code is working now but it is not plotting in the colorwise
manner ie, khaki4 and indian red. Maybe I need to work more. If you have
any clue then please let me know.
Thanks again,
Puja
