This is the first code seen at that page:

source("http://bioconductor.org/biocLite.R;)
biocLite("GEOquery")

You were told earlier that rhelp is NOT the correct place to post questions 
about Bioconductor packages. What is the cause of your difficulty in 
understanding this fact?

  I'm not familiar with Elliptic Fourier Analysis, so I don't know 
what other search terms might be helpful for this.



  A similar search at "http://rdocumentation.org; produced nothing

  However, the building blocks for what you need are most likely 
available in R.

Re: [R] about data format in R

2016-12-31 Thread lily li 
Thanks. It seems that substrings only subset the data, not convert the
format. For example, I use the code below:
DF$time = substring(DF$time, '%Y-%m-%d')

where DF$time has the structure:
'2002-01-01 00:00:00', '2002-01-01 12:00:00', '2003-01-01 00:00:00',
'2003-01-01 12:00:00', etc.
I wanted to convert the 'time' column to '2002-01-01', '2002-01-01',
'2003-01-01', '2003-01-01', etc.

Using the code above, it gives the error message:
Error in as.POSIXlt.character(as.character(x), ...) :
  character string is not in a standard unambiguous format

Thanks for your help. Now I can convert data to the format "-mm-dd
