R as a Tool for Statistical Analysis Getting Started with R (Part I) The > is called the prompt. If a command is too long to fit on a line‚ a + is used for the continuation prompt. Assign values to an object using the equal sign (=)‚ e.g.‚ >x=11. Note: R is case sensitive Print command allows you to see the value in an object You may also use the less than sign and a dash to create an arrow (<-) to assign values. An equal sign (=) is also used to assign values. R easily overwrites

The movie 21 There is one thing I like in this movie‚ Trick math and card counting was one of the fascinating thing in the movie and the introduction of the principle of variable change (The Monty hall problem and conditional probability). A game show host tells a contestant to choose between three doors. Two doors have a goat behind them…and the other has a brand new car. He tells the contestant to choose a door.

GENERAL BIOCHEMISTRY Problem Set No. 1 Answered by: Andrea Rose A. Fajardo of BSFT 2-1N 1. Calculate the pH of a dilute solution that contains a molar ratio of potassium acetate to acetic acid (pKa=4.76) of: a. 2:1 pH = 4.76 + log[2]/[1] = 4.76 + 0.3010 = 5.06 b. 1:4 pH = 4.76 + log[1]/[4] = 4.76 + (-0.6021) = 4.16 c. 6:5 pH = 4.76 + log[6]/[5] = 4.76 + 0.0792

action alone causes transformation. Transformation is not just change. Change is often reversible and external. But transformation is lasting and happens from within. A caterpillar transforms into a butterfly. A child transforms into a youth and an adult. A country transforms into a nation. A nation transforms from a developing nation to a developed nation. We have transformed as a country to attain political freedom and have come a long way since then. We have the potential to lead the world

The horizons of optical networks are much more than high speed physical layer transport. An intelligent optical network design must include higher network layer considerations. This is the only book currently on the market that addresses optical networks from the physical layer to the network layer and should be valuable for those who try to understand the intricacies of what optical networks can be. —Vincent Chan‚ Professor‚ MIT Department of Electrical Engineering and Computer Science This book

Dependencies and Network Diagram The network diagram is a schematic representation showing the sequence and relationship/ dependency of the tasks along with their duration. All the tasks‚ except the first and the last‚ are linked with at least one predecessor and successor to have a proper sequence of work. This logical dependency between the tasks will determine afterwards the duration of the project. There are four types of dependencies which define the relation between pair tasks Finish-to-start
