Hi all, I can not seem to get what I want using the Lattice package to generate an array of histograms of spatialgrid dataframe data. I can use the sp package and spplot to generate an array of maps that display an array of spatialgrid dataframe data -- that's good. I have: spplot(ann_bias,xlim=c(1423987.5,2614612.5),ylim=c(-5862637.5,-4624387.5),at=brks,col.regions=colp(length(brks)-1),main="NOAA/NWS OHRFC Stage-3/MPE Precipitation Estimate Bias with respect to PRISM\n1997 - 2016") Which works... I can also do histogram(ann_bias$bias1997), which works too. I have also cre...

Hello all, After more digging I was able to find out how to do this. The answer came from an example here: https://stackoverflow.com/questions/3541713/how-to-plot-two-histograms-together-in-r yr_1997<-data.frame(bias=ann_bias$bias1997) yr_1998<-data.frame(bias=ann_bias$bias1998) yr_1999<-data.frame(bias=ann_bias$bias1999) yr_2000<-data.frame(bias=ann_bias$bias2000) yr_2001<-data.frame(bias=ann_bias$bias2001) yr_2002<-data.frame(bias=ann_bias$bias2002) yr_2003<-data.frame(bias=ann_bias$bias2003) yr_2004...

...estions below). In the future, follow the recommendations of the Posting Guide: use plain text, and provide a reproducible example. Some elaborations on what "reproducible" means are [1][2][3]. One issue here was that you did not include sample data to work with (I have assumed below that ann_bias has no other columns than the biasNNNN columns, which is not the usual case). There are a number of ways to achieve the reshaping of your ann_bias data frame that are less painful than your approach. For example, the base R "stack" function: bias2 <- stack( ann_bias ) names( bias2 )...
