How to use R functions search and objects to find all possib

Solution

search() function gets the list of attached packages in the R search path.R has many built in functions.

The R built in functions related to normL distribution are dnorm(x,mean = 0, sd = 1, log = FALSE)

pnorm(q, mean = 0, sd = 1, lower.tail = TRUE, log.p = FALSE,)

qnorm(p, mean = 0, sd = 1, lower.tail = TRUE, log.p = FALSE)

rnorm(n, mean = 0, sd =1)

x,q - vector of quintiles

p - vector of probabilities

n - number of observations

mean - vector of means

sd- vector of standard deviations

log, log.p - logical; if TRUE, probabilities p are given as log(p)

lower.tail - logical; if TRUE (default), probabilities are P[X<=x], otherwise P[X>x]
