ag.ds.contourplot: Creates a contour plot

In datashield/ag.dev.cl: ag.dev.cl

Description

Generates a contour plot of the given data values.

Usage

  ag.ds.contourplot(opals, xvect, yvect, type = "combine",
    numints = 20)

Arguments

opals	character strings that represent the URL of the servers where the study datasets are stored.
xvect	a numerical vector
yvect	a numerical vector
type	a character which represents the type of graph to display. If type is set to 'combine', a combined contour plot displayed and if type is set to 'split', each conntour is plotted separately.
numints	a number of intervals for a density grid object

Value

a contour plot

Examples

{
# load the file that contains the login details
data(logindata)

# login and assign the required variables to R
myvar <- list("LAB_TSC","LAB_HDL")
opals <- ag.ds.login(logins=logindata,assign=TRUE,variables=myvar)

# Example1: generate a combined contourplot
ag.ds.contourplot(opals, quote(D$LAB_TSC), quote(D$LAB_HDL), type="combine")

# Example2: generate a contourplot where each study is plotted seaparately
ag.ds.contourplot(opals, quote(D$LAB_TSC), quote(D$LAB_HDL), type="split")

# Example3: generate a contourplot with a less dense drid
ag.ds.contourplot(opals, quote(D$LAB_TSC), quote(D$LAB_HDL), type="split", numints=15)
}
