Some learners say that they feel R is mix of MATLAB and SAS if I were to relate to the other 2 tools used in Finance. R is having mix of maths and data handling powers of SAS and given that it is open source it is the best choice for research. R is MATLAB when it comes to syntax. When it comes to data handling it uses R MySQL in the very same way as SAS does. Hence it does things that SAS+MATLAB do for free. SQL has inherent limitations of doing quant computations, and MATLAB is heave and requires too much resources. MATLAB is not very good to deal with SQL at system level. But to start with one needs to also know VBA as for entry level and easy task VBA is preferred.

Also, you would learn the application of R for quantitative finance.

Functions of R / R Commands to be covered in the course:


Always save workspace

Use “c” when you want to use it a signal in black schools formula

 read.table function will be used to get the data into R (/\ used opposite than the one used in windows)


Example 1

> test.txt <- read.table (“C:/Documents and Settings/shivbhakta.joshi/My

Documents/test.txt”, header=T)

> print(test.txt)

> column <- test.txt[,c(‘make’,’price’)]

Example 2

grb <- read.table (“C:/Documents and Settings/shivbhakta.joshi/My

Documents/GRB_afterglow.dat”, header=T, skip=1)

x <- (grb[,1])


Grabbing data from tables into an single dimensional arrayx <- (grb[,1])

y <- log(grb[,1])

Another way to create returns for stock daily return is

f=dft$age/dft$price (using dollar sign extraction)

Deleting column http://www.sr.bham.ac.uk/~ajrs/R/r-manipulate_data.html

> add <- add[-2] to delete the element 2nd

Adding data to array busing column command

> add <- c(1,d)


Using Data frames

Data.frame is used to combine the arrays back into table format

people = data.frame (x,y)

Write.CSV command executed


grb <- read.table (“C:/Documents and Settings/satyadhar.joshi/My

Documents/GRB_afterglow.dat”, header=T, skip=1)

x <- (grb[,1])

y <- log(grb[,1])

people = data.frame (x,y)


These methods can be used to compute beta from columns of a csv file


Working formula of Blach Scholes

BS <-

function(S, K, T, r, sig, type=”C”){

d1 <- (log(S/K) + (r + sig^2/2)*T) / (sig*sqrt(T))

d2 <- d1 – sig*sqrt(T)


value <- S*pnorm(d1) – K*exp(-r*T)*pnorm(d2)



value <- K*exp(-r*T)*pnorm(-d2) – S*pnorm(-d1)





blackscholes <- function(s, k, r=.1, t=5, sigma=.9,call=TRUE) {

#calculate call/put option

d1 <- (log(s/k)+(r+sigma^2/2)*t)/(sigma*sqrt(t))

d2 <- d1 – sigma * sqrt(t)

ifelse(call==TRUE,s*pnorm(d1) – k*exp(-r*t)*pnorm(d2),k*exp(-r*t)

* pnorm(-d2) – s*pnorm(-d1))



Predefined Black schools model:


black_scholes (“c”,5600,5600,.1,.08,.22 )

this depicts use of functions in R


Merton Distance to Default (different as per needs)

(modified from Black Scholes formula, still

unsure about pnorm() function)

d1 <- (log(s/k)+(sigma^2/2))/(sigma)



3 files needed to run the demos are available on internet by various authors:

  1. black_scholes.R
  2. GRB_afterglow.dat
  3. test.txt
