btb 0.2.0

• Change of maintainer, new authors (november 2022)
• Change dfToGrid name (to btb_ptsToGrid)
• Allow btb_ptsToGrid to use simple feature points as input
• Change kernelSmoothing name (to btb_smooth)
• Allow btb_ptsToGrid to use simple feature points as input
• New function to link points to their centroid in a grid (btb_add_centroides)
• Updates messages when smoothing removed (in RcppLissage.cpp)
• Old functions dfToGrid and kernelSmoothing replaced by warnings
• Possibility to use Inspire naming for grid cells (with btb_add_inspire function)
• Roxygen documentation
• testthat compatible tests
• New tests
• Add vignette
• Add pkgdown website

btb 0.1.30.3

• New CRAN version (last version submitted by Arlindo)

btb 0.1.19

• improvement: ckecking if NA exists in coordinates and variables with a loops (faster than anyNA)
• improvement: two matrix suppressed in parameters sended to rcppLissage
• new function : constituerGrappes
• new function : constituerMatriceEffectifs

btb 0.1.18

• improvement: kernelSmoothing uses armadillo matrix instead of NumericMatrix

btb 0.1.17

• improvement: kernelSmoothing with quantiles splits computation in parallel clusters (with RcppParallel)

0.1.16

• improvement: smoothingToGrid uses sf package instead of sp package

btb 0.1.15

• improvement: verbose output to console only if fUpdateProgress is not provided. (if provided, the output must be managed by the calling function)
• improvement: use of left-value [, "var"] instead of $var

btb 0.1.13

• bug fixed: upper boundary of loop for was underestimated when bandwidth > neighbor o cellSize
• bug fixed: the offset was wrong when dfCendroids was provided
• improving window when looking for cells to send smoothed value
• new argument for kernelSmoothing and smoothingToGrid: fUpdateProgress
• neighbor argument is 0 if dfCendroids is provided
• adding this NEWS file
• adding unit tests
• encoding in UTF-8 (description file)

btb 0.1.3

• change c++ library call for solaris compatibility

btb 0.1.2

• bug fixed: manage missing values
• bug fixed: doubles comparison
• rename bandwith in bandwidth
• improved documentation
• improved memory improved (double to int when possible)
• kernelSmoothing accept a new argument: dfCentroids
• new smoothing mode: mobile quantile
• log when na value is found
• check if bandwidth > sqrt(cellSize) / 2
• check if x and y are not null
• encoding source files in UTF-8

btb 0.1.1

• small bugs correction

btb 0.1.0

• kernelSmoothingMedian function

btb 0.0.7
