I have run the LightImage function as part of the FLightR script many times without any issues, but recently it "stopped working". I have updated various packages, R studio and R versions, but I don't see why I'm now getting the error I do. > d.lux$Light<- log(d.lux$Light) > head(d.lux) Date Light 1 2013-04-20 15:14:01 6.302619 2 2013-04-20 15:19:01 5.159055 3 2013-04-20 15:24:01 5.257495 4 2013-04-20 15:29:01 5.594711 5 2013-04-20 15:34:01 5.181784 6 2013-04-20 15:39:01 4.663439 > lightImage(tagdata = d.lux, + offset = offset, + zlim = c(0, 12), # y axis + dt = 300) # recording interval in seconds (300 if every 5min) Error in if (as.numeric(tmax) < as.numeric(date[length(date)])) tmax <- tmax + : missing value where TRUE/FALSE needed > sessionInfo() R version 3.4.2 (2017-09-28) Platform: x86_64-w64-mingw32/x64 (64-bit) Running under: Windows >= 8 x64 (build 9200) Matrix products: default locale: [1] LC_COLLATE=English_United Kingdom.1252 [2] LC_CTYPE=English_United Kingdom.1252 [3] LC_MONETARY=English_United Kingdom.1252 [4] LC_NUMERIC=C [5] LC_TIME=English_United Kingdom.1252 attached base packages: [1] grid stats graphics grDevices utils datasets methods [8] base other attached packages: [1] maptools_0.9-2 sp_1.2-5 MASS_7.3-47 SGAT_0.1.3 [5] TwGeos_0.0-1 GeoLight_2.0.0 maps_3.2.0 FLightR_0.4.6 [9] BAStag_0.1.3 loaded via a namespace (and not attached): [1] Rcpp_0.12.13 lattice_0.20-35 changepoint_2.2.2 zoo_1.8-0 [5] spam_2.1-1 coda_0.19-1 raster_2.5-8 tools_3.4.2 [9] foreign_0.8-69 fields_9.0 compiler_3.4.2 dotCall64_0.9-04 > Any thought?
