I am a Biologist and a beginner, please help me to solve this: please anyone..its my homework and I dont have a clue abt R yet.. Write a function which does the following tasks: (a) Calculates minimum and maximum value of a given argument x. (b) If x is positive, some new vector gets the value of TRUE, and FALSE otherwise. (c) Creates a vector where the i:th and (i-1):th values of x are always summed. First value of the new vector has the same value as the first component of x. Use the created function to some vector x to show that the function works. -- View this message in context: http://r.789695.n4.nabble.com/Biologist-R-learner-tp4650044.html Sent from the R help mailing list archive at Nabble.com.

Please read the posting guide: http://www.r-project.org/posting-guide.html R-help is not for homework. Read the introductory manual "An Introduction to R" (links are on the page for the posting guide.) Berend
Please take the advice of Berend if you ever want to get help here. Also, you will need to do some basic and initial work yourself; read what he suggested, use Google to search keywords, and see great help like this: http://cran.r-project.org/doc/contrib/Short-refcard.pdf also, use the built in help pages by using a question mark like this: ?min ?max ?ifelse ?cumsum Good luck; don't let a sharp learning curve stop you from learning R.
