similar to: follow up on teaching R to high school students

I participate peripherally on a listserve for middle- and high-school science teachers. Sometimes questions about graphing or data analysis come up. I never miss an opportunity to advocate for R. However, the teachers are often skeptical that their students would be able to issue commands or write a little code; they think it would be too difficult. Perhaps this stems from the Microsoft- and

Hey Everyone, I''ve been working on putting this project together for a few weeks now and it is finally coming together. The "Workshop for Good" will take place Saturday and Sunday May 20th - 21st.

Hi folks, I''m working with a local high school in the Portland, OR area on the subject of computer science curriculum. We are thinking of introducing a class in web development and I think Rails would be a perfect vehicle. I''ve done some searching on the web but haven''t found any suggestion of HS curriculum for Rails. Any pointers or suggestions? Thanks, ---

Only I didn't laugh The teacher often in class education everyone said, when seeing other defects and unfortunately, wholesalers:www.smbuys.com 10 million don't laugh at. One day, the little brown told the teacher say: "today have a campus a child fell into the puddle, everyone laugh, only I didn't laugh" "you do it right." teacher, "who praised fell into the

Every day I get a csv file containing the names of the 64 schools in our county, the number of students sent home ill, and the number of students absent (plus lots of other variables). The file is cumulative since fall of 2009. It is in "long" format: one line per school per day. Each line is also supposed to contain the total number of students enrolled in the school. That number

Hi all, Last week I implemented samba a sa file server and domain controller for more than 150 computers (Win 2000 and XP). Everything is working just fine. However, computer science faculty wanted a share for each course in which students can upload their homework once done and teacher download them for correction. Yet, students can have the right to write on that share but not delete the work

I have a column in which dates and times are specified thus m/d/yyyy HH:MM:SS Alas, some entries do not include the time and therefore are only m/d/yyyy so I used read.csv and specified that the relevant column should be read as is and it remained as a character variable. I then split the value on the space split.dt.time <-strsplit(teacher$Date.and.Time.of.Lesson," ") that gives me a

The ts method for plot() is quirky.

How would I color points conditional on their value in a plot of a time series. Something like this: ## demonstration data ttt <- ts(rpois(12, lambda = 8), start = c(2000, 1), freq = 4) ttt plot(ttt, type = "p") ## doesn't work--all points the same color plot(ttt, type = "p", col = ifelse(ttt < 8, "black", "red")) ## also doesn't work--all
