Development

In October 1968 Cessna announced an eight place business jet capable of operating from light/medium twins airfields.
The Fanjet 500 prototype first flew on September 15, 1969.
The renamed Citation had a relatively long development program with a longer forward fuselage, repositioned engine nacelles, a larger tail and more dihedral to the horizontal tail.
It was FAA certified on September 9, 1971.[3]


In early 1976, its wing span grew from 43.9 to 47.1 ft (13.4 to 14.4 m).[4]
It also gained thrust reversers and higher gross weights.
The enhanced Citation I was introduced later in 1976 with higher weights, JT15D-1A engines and an increased span wing.
The 501 Citation I/SP, certificated for single pilot operations, was delivered in early 1977.
Production ended in 1985, it was developed into the Citation II/Bravo and the Citation V/Ultra/Encore.
Over 690 Citations, Citation Is and I/SPs were built between 1971 and 1985.[3]



Design

The aircraft was powered by two Pratt & Whitney Canada JT15D-1 turbofan engines after Cessna's experience with the T-37 Tweet twinjet trainer.
Turbofan rather than turbojets and straight wings rather than swept wings made it cruise slowly compared to other business jets and Learjet salesmen mocked it as the “Nearjet” vulnerable to “bird strikes from the rear”; Cessna renamed it the “Citation” after the thoroughbred but it was nicknamed as “Slowtation”.[5]

In R, how to develop a multiplot heatmap.2 figure showing key labels successfully

1 2 I'm trying to develop a multiplot heatmap.2 saved to a pdf. I'm having some success but the axis labels are getting chopped off. Subplot titles are also desirable but again the labels are getting chopped. Here's my reproducible code: library(gridExtra) library(grid) library(gridGraphics) library(gplots) Col = colorRampPalette(c("red","orange","yellow", "white")) grab_grob <- function() grid.echo() grid.grab() par(cex.main=0.1, mar = c(1,1,1,1) ) #data<-read.table("heatmap.input.matrix.data.txt") lmat = rbind(c(2,3),c(4,1),c(4,1)) lwid = c(2.5,4) lhei = c(0.5,4,3) labRowvec <- c(rep(NULL, dim(matrix(runif(1000, 1,10),ncol=50))[1])) labColvec <- c(rep(NULL, dim(matrix(runif(1000, 1,10),ncol=50))[2])) gl <- lapply(1:12, function(i) heatmap.2(matrix(runif(1000, 1,10),ncol=50), dendrogram = "none",offsetRow=-0.5, offsetCol=-1,srtCol=0, density="density", lmat =lmat,lhei = l
