Hi, It would be great if someone could help me figure this out. When I run the following code: proc gplot; plot x*y=z; run; quit; The "y" variable is categorical with 2 categories and the 2 categories are on 2 ends of the xaxis, very, very close to the vertical borders of the plot. How can I move the categories to the middle so that there is some empty space between the category and the border/y axis Thanks! ... View more

Hello, I am running into this issue and it would be great if someone can help me out. I am using the following statements: goptions vsize=5 hsize=7 gunit=pct cback=white horigin=0.5          ftext=swiss ftitle=swissb htitle=3 htext=3; symbol value=dot interpol=hilobj; proc gplot data=all; plot y * instrument = sample; run; Since I have about 30 samples, SAS seems to be running out of colors and after 12 samples, it starts with the same set of colors but now with other symbols. And, most importantly, it is not drawing those lines connecting the samples (across the 3 instruments) once it switches to the different symbol-so I have lines joining the first 12 samples only. Is there a way to make SAS draw the lines for all the samples (i.e. make SAS use only dots and some more colors additional to the first 12)? Thanks so much for reading! ... View more

My experiment design is as follows. Each sample in the experiment is run on 2 “kit”s. Each "kit" has 2 “operator”s. Each operator performs the experiment in 2 “lab”s. And,each of these combinations uses a different “part” of the sample-that’s a total of 8 different “part”s from the sample run randomly on different “kit-operator-lab” combinations. (another option is to use 4 "part"s from the same sample and run the same combination on the 2 kits) All the variables "kit, operator, lab" are random effects and I would like to estimate the variance due to each of these. It would be very helpful to know how to specify these effects in the "random" statement. Something like this? proc mixed; class kit operator room part; model y=; random kit operator*lab part(kit); run; Thanks! ... View more

I always get great ideas when I post here and hence the question. I ran the following model: proc mixed ; class lot operator instrument run tube sample day; model response= ; random sample day lot tube operator instrument run; run; Now, I have been asked to include within-run and between-run variability in the table(where I represented all the variance estimates as a % of the total). Any thoughts? I tried a few things but not quite there yet. Thanks ... View more

I am importing several excel files-all in the same format so that I can then set them all one below the other in a single dataset. Thes ample name has values like A1, B2, etc. It only runs upto A9 (total of 2 characters) in one file but has more than 2 characters in some other excel files. When I use the "set" statement to set all these datasets to a single dataset, the sample name gets truncated to 2 characters. How do I make sure I retain the entire name and also uniformity in the variable length? Thanks ... View more

I would like to specify a value of '1' to my slope and estimate the intercept. Is there a way to do that in proc GLM or another proc? Thanks ... View more
