# calcFreqs: calcFreqs In bertamiro/lpattern: Detection of scatterplots with L-shaped pattern

## Description

`calcFreqs` Given two numeric vectors this function overimposes a grid on the scatterplot defined by YMet~Xmet #' and returns a 3X3 matrix of counts with the number of points in each cell of the grid #' for given vertical and horizontal lines.

## Usage

 ```1 2``` ```calcFreqs(xMet, yExp, x1, x2, y1 = NULL, y2 = NULL, percY1 = 1/3, percY2 = 2/3) ```

## Arguments

 `xMet` First numeric vector which, in principle, contains the methylation values. `yExp` Second numeric vector which, in principle, contains the expression values. `x1, x2` Coordinates of vertical points in the X axis. Because it is expected to contain methylation values that vary between 0 and 1 the default values are 1/3 and 2/3. `y1, y2` Coordinates of vertical points in the Y axis. Leaving them as NULL assigns them the percentiles of yVec defined by 'percY1' and 'percY2'. `percY1, percY2` Values used to act as default for 'y1'and 'y2' when these are set to 'NULL'

## Examples

 ``` 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17``` ```## Not run: data(trueGenes) xVec<- as.numeric(myMetilData[trueGene1,]) yVec<-as.numeric(myExprData[trueGene1,]) titolT <- trueGene1 plotGeneSel(xMet=xVec, yExp=yVec, titleText=titolT, x1=1/3, x2=2/3) messageTitle(paste("Cell counts for gene",trueGene1)) calcFreqs(xMet=xVec, yExp=yVec, x1=1/3, x2=2/3, y1=NULL, y2=NULL, percY1=1/3, percY2=2/3) xVec<- as.numeric(myMetilData[falseGene1,]) yVec<-as.numeric(myExprData[falseGene1,]) titolF <- falseGene1 messageTitle(paste("Cell counts for gene",falseGene1)) plotGeneSel(xMet=xVec, yExp=yVec, titleText=titolF, x1=1/3, x2=2/3) calcFreqs(xMet=xVec, yExp=yVec, x1=1/3, x2=2/3, y1=NULL, y2=NULL, percY1=1/3, percY2=2/3) ## End(Not run) ```
