The November Chomp App Search Analytics report is out! The official Chomp blog post can be found here. The quick summary is:
search traffic for the terms shopping and discounts spiked more than 1300% and 3000%, respectively on Black Friday and returned to normal on Cyber Monday
I highlight tons of great Holiday Apps and Games to keep you busy through the season
After looking up how to create a legend using ?legend and searching the R forums for the 86586586th time, I’ve decided to write my own post with a few examples and tricks I’ve picked up. I also provide example code for using dates as an x-axis.
I do most of my heavy computation in Python, leaving R for primarily making pretty plots, exploratory data analysis (EDA) when I first get my hands on a data set, and using my favorite R packages/functions that I’ll never implement on my own (ie Random Forests, CART, SVM). Below is an example plot, with two sets of numbers, a legend, and dates on the axis. Hopefully this is more helpful than the R documentation.
# pick a length, and generate two random normals of this length
len = 43
vals = rnorm(len,0,1)
vals2 = rnorm(len,0,.5)
# pick an initial date in form YYYYMMDD, then generate a years worth of weekly dates
date = 20110201
mydates<-as.Date(as.character(date),"%Y%m%d")
for(i in 1:52){ #
mydates = c(mydates,mydates[length(mydates)]+7)
}
# rename something shorter
x=mydates[2:(len+1)]
# set graphical parameters and plot both random normals, use xaxt="n" to eliminate the x-axis
par(mfrow=c(1,1))
plot(vals,type="l",col="blue",xaxt="n",ylab="y axis label",xlab="",main="Plot Title")
lines(vals2,col="red")
# add back an x-axis with dates, las and cex.axis set direction and size of dates
axis(1, at=1:len,x,las=2,cex.axis=.9)
# add a legend, lwd sets line width, you can use x,y coordinates instead of "bottomleft"
legend("bottomleft", c("thing1","thing2"), col = c("blue", "red"), lwd = 1, title="legend title")
I’m still powering through all the recipe posts I wanted to do after Rosh Hashanah, so here’s the latest, the best noodle kugel recipe ever. It’s my grandmother’s, so I know that slightly biases me, but I’ve had at least 10 people tell me it’s better than their grandmothers’. First here’s a pic of all the ingredients:
The full ingredient list is:
1 pkg egg noodles.
cook, drain, put in large pot and add
1/2 cup sugar
1 cup sour cream
1 container cottage cheese
3 eggs beaten
1 sm can crushed pineapple with juice
1 stick melted margarine (butter)
1 apple grated (thick)
1 teaspoon vanilla
1.5 teaspoon cinnamon
Beat eggs then add all other ingredients, cottage cheese last. When fully mixed the ingredients should smell like kugel and have roughly this consistency:
Mix well put in large baking pan sprinkle with crushed cornflake crumbs and dot with butter. Bake 1 hour at 350 and it should look like this:
Last, but certainly not least, here’s a pic of my grandmother (right) and me as its her recipe:
