Re: [R] [FORGED] Re: How create columns for squared values from previous columns?

I thought it's just deleting and reassigning those specific columns. I guess I don't know R as much as I think I do. :( On Sat, Apr 29, 2017 at 4:06 AM, Göran Broström wrote: > > > On 2017-04-29 06:45, Mike C wrote: > >> Thanks Rolf. I was just a bit frustrated that R wouldn't generate >> dummy

Re: [R] Finding nrows with specefic values&converting a matrix into a table

First. Do not use html messages, only plain text. Second. Provide a small example data set, preferably using dput(). Just printing your data can hide important information. Third. Read the documentation. Your first example does not return a logical vector at all: > dput(mydata) structure(list(C

Re: [R] Matrix-list table conversion+nrwos with specefic values.

Break it down. If you have a scalar value val and you want to know if it is in a vector vec, using val==vec gets you a logical vector as long as vec. You can use val %in% vec and you get a logical vector as long as val (e.g. 1). If val is a vector of, say, length 2, then you will get a length 2

Given that, you can be certain that your file contains more than one or two numbers, thus your way of reading it must be wrong. B. > On Apr 29, 2017, at 11:34 AM, Ragia . wrote: > > > files size is 7682 kb > > sorry for multiple emails > > Ragia > > > > > ___

1. Unless your comment is OT or personal, always reply to the list. 2. What does your OS say about file size? 3. Beyond this, I cannot help. -- Bert Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking things into it." -- Opus (aka Berkeley Breathed
