Omar, please remember that this is R-help, not R-do-my-work-for-me... you have
already been given several hints as to how you can refine your patterns
yourself. These skills are key to real world data science, so you need to work

Hi Ace,
With tabs as separators:
testdf<-read.table("test.txt",header=FALSE,fill=TRUE,sep="\t",
col.names=paste("V",1:19,sep=""),stringsAsFactors=FALSE)
Also note that I got the number of columns wrong the first time.

Hi Ace,
As your example seems to have spaces as separators,
testdf<-read.table("test.txt",header=FALSE,fill=TRUE,
col.names=paste("V",1:14,sep=""),stringsAsFactors=FALSE)
By specifying the number of columns with "col.names" and using
"fill=TRUE" you can get a data frame with zero length strings w
Email a mess. Too hard for me to decipher, maybe also for others.
If no response, send plain text, as requested by posting guide.

I don't think this can work. For example number-letter patterns 4),

Good evening!
I don't know R, but I have to do this work for my diploma. So I'm sorry for
the strange message below. Help me anybody decides this issues, please.
a part of the code is:

r_squared <- vector()
sample_bank <- mydata[((i-1)*311+1):(i*311),]
#return for bank

Just a quick note:
"I have tried to use optimr but it gives me the local maxima, now I am
struck with the problem of how to get the global maxima"
This is a profound misunderstanding of how numerical optimization
works. **All** numerical optimizers can provide only "local" maxima

And also to the initial error message
I suggest the message be revised to say

You may have to provide us more detail on **exactly** the sorts of
patterns you wish to "capture" -- including exactly what you mean by
"capture" (what vaue do you wish to return?) -- as the "obvious"
answer is probably not sufficient:

Clearly you are being too specific about the structure of the sku. In the
absence of better information about the sku you need to focus on identifying
the delimiters and position of the sku... one way might be:
ecommerce$sku <- sub( "^(.*)[ \n]+([^ \n]+)$", "\\2", ecommerce$producto )

Hello, I need some help with regex.
I have this to sentences. I need to extract both "49MU6300" and "LE32S5970"
and put them in a new colum "SKU".
A) SMART TV UHD 49'' CURVO 49MU6300
B) SMART TV HD 32'' LE32S5970
DataFrame for testing:
ecommerce <- data.frame(a = c(1,2), producto = c("SMART TV
I have not followed the history of this thread, but I am quite flummoxed as to
why the OP is rewriting code to estimate parameters from an univariate Gaussian
mixture model when alternatives such as EMCluster (which generally appears to
handle initialization better than MClust) exist. Or perhaps
Dear Niharika,
As I said before, the problem is basically an optimization issue. You should
isolate the problematic part from the rest of your study. Sometimes, more
information does not help to solution. All the answers from us (Ulrik, David,
me) are more or less are correct to find a maximum
